7105a78b17 ui-tree: use "sane" isgraph()
Git's git-compat-util.h defines a "sane ctype" that does not use locale
information and works with signed chars, but it does not include
isgraph() so we have included ctype.h ourselves.

However, this means we have to include a system header before
git-compat-util.h which may lead to the system defining some macros
(e.g. _FILE_OFFSET_BITS on Solaris) before git-compat-util.h redefines
them with a different value.  We cannot include ctype.h after
git-compat-util.h because we have defined many of its functions as
macros which causes a stream of compilation errors.

Defining our own "sane" isgraph() using Git's sane isprint() and
isspace() avoids all of these problems.

30304d8156 log: allow users to follow a file
Teach the "log" UI to behave in the same way as "git log --follow", when
given a suitable instruction by the user.  The default behaviour remains
to show the log without following renames, but the follow behaviour can
be activated by following a link in the page header.

Follow is not the default because outputting merges in follow mode is
tricky ("git log --follow" will not show merges).  We also disable the
graph in follow mode because the commit graph is not simplified so we
end up with frequent gaps in the graph and many lines that do not
connect with any commits we're actually showing.

We also teach the "diff" and "commit" UIs to respect the follow flag on
URLs, causing the single-file version of these UIs to detect renames.
This feature is needed only for commits that rename the path we're
interested in.

For commits before the file has been renamed (i.e. that appear later in
the log list) we change the file path in the links from the log to point
to the old name; this means that links to commits always limit by the
path known to that commit.  If we didn't do this we would need to walk
down the log diff'ing every commit whenever we want to show a commit.
The drawback is that the "Log" link in the top bar of such a page links
to the log limited by the old name, so it will only show pre-rename
commits.  I consider this a reasonable trade-off since the "Back" button
still works and the log matches the path displayed in the top bar.

Since following renames requires running diff on every commit we
consider, I've added a knob to the configuration file to globally
enable/disable this feature.  Note that we may consider a large number
of commits the revision walking machinery no longer performs any path
limitation so we have to examine every commit until we find a page full
of commits that affect the target path or something related to it.

a3722ec3c6 Add a cache-snapshot-ttl configuration variable
This can be used to specify the TTL for snapshots. Snapshots are usually
static and do not ever change. On the other hand, tarball generation is
CPU intensive.

One use case of this setting (apart from increasing the lifetime of
snapshot cache slots) is caching of snapshots while disabling the cache
for static/dynamic HTML pages (by setting TTL to zero for everything
except for snapshot requests).

d6e9200cc3 auth: add basic authentication filter framework
This leverages the new lua support. See
filters/simple-authentication.lua for explaination of how this works.
There is also additional documentation in cgitrc.5.txt.

Though this is a cookie-based approach, cgit's caching mechanism is
preserved for authenticated pages.

Very plugable and extendable depending on user needs.

The sample script uses an HMAC-SHA1 based cookie to store the
currently logged in user, with an expiration date.

e83b51b4f6 filter: basic write hooking infrastructure
Filters can now call hook_write and unhook_write if they want to
redirect writing to stdout to a different function. This saves us from
potential file descriptor pipes and other less efficient mechanisms.

We do this instead of replacing the call in html_raw because some places
stdlib's printf functions are used (ui-patch or within git itself),
which has its own internal buffering, which makes it difficult to
interlace our function calls. So, we dlsym libc's write and then
override it in the link stage.

While we're at it, we move considerations of argument count into the
generic new filter handler.

d750c7a2c9 filter: allow for cleanup hook for filter types
At some point, we're going to want to do lazy deallocation of filters.
For example, if we implement lua, we'll want to load the lua runtime
once for each filter, even if that filter is called many times.
Similarly, for persistent exec filters, we'll want to load it once,
despite many open_filter and close_filter calls, and only reap the child
process at the end of the cgit process. For this reason, we add here a
cleanup function that is called at the end of cgit's main().

pointers on the cgit_filter object.

We treat the "exec" filter type slightly specially here by putting its
structure definition in the header file and providing an "init" function
to set up the function pointers.  This is required so that the
ui-snapshot.c code that applies a compression filter can continue to use
the filter interface to do so.

b1f17f168b Fix out-of-bounds memory accesses with virtual_root=""
The CGit configuration variable virtual_root is normalized so that it
does not have a trailing '/' character, but it is allowed to be empty
(the empty string and NULL have different meanings here) and there is
code that is insufficiently cautious when checking if it ends in a '/':

	if (virtual_root[strlen(virtual_root) - 1] != '/')

Clearly this check is redundant, but rather than simply removing it we
get a slight efficiency improvement by switching the normalization so
that the virtual_root variable always ends in '/'.  Do this with a new
"ensure_end" helper.

521e10c884 scan-tree: Unify gitweb.* and cgit.* settings into one config option.
After some back and forth with Jamie and René, it looks like the git
config semantics are going to be like this:

- gitweb.category maps to the cgit repo config key "section"
- gitweb.description maps to the cgit repo config key "desc"
- gitweb.owner maps to the cgit repo config key "owner"
- cgit.* maps to all cgit repo config keys

This option can be enabled with "enable-git-config=1", and replaces
all previous "enable-gitweb-*" config keys.

The order of operations is as follows:

- git config settings are applied in the order that they exist in
  the git config file
- if the owner is not set from git config, get the owner using the
  usual getpwuid call
- if the description is not set from git config, look inside the
  static $path/description file
- if section-from-path=1, override whatever previous settings were
  inside of git config using the section-from-path logic
- parse $path/cgitrc for local repo.* settings, that override all
  previous settings

a1429dbc89 cgit.c: add 'clone-url' setting with support for macro expansion
The current 'clone-prefix' setting has some known issues:
* All repos get the same 'clone-prefix' value since the setting is not
  adopted during repo registration (in cgitrc, or during scan-path traversal),
  but only when the setting is used.
* The generated clone-urls for a repo is a combination of 'clone-prefix', a
  slash and the repo url. This doesn't work well with e.g. ssh-style urls
  like 'git@example.org:repo.git', since the inserted slash will make the
  repo relative to the filesystem root.
* If 'remove-suffix' is enabled, the generated clone-urls will not work for
  cloning (except for http-urls to cgit itself) since they miss the '.git'
  suffix.

The new 'clone-url' setting is designed to avoid the mentioned issues:
* Each repo adopts the default 'clone-url' when the repo is defined. This
  allows different groups of repos to adopt different values.
* The clone-urls for a repo is generated by expanding environment variables
  in a string template without inserting arbitrary characters, hence any
  kind of clone-url can be generated.
* Macro expansion also eases the 'remove-suffix' pain since it's now
  possible to define e.g. 'clone-url=git://foo.org/$CGIT_REPO_URL.git' for
  a set of repos. A furter improvement would be to define e.g.
  $CGIT_REPO_SUFFIX to '.git' for all repos which had their url prettified,
  or to store the original $CGIT_REPO_URL in e.g. $CGIT_REPO_REAL_URL before
  suffix removal.

3ec6b30950 cgit.c: always setup cgit repo environment variables
When cgit learned to setup environment variables for certain repo
settings before invoking a filter process, the setup occurred inside
cgit_open_filter().

This patch moves the setup out of cgit_open_filter() and into
prepare_repo_cmd() to prepare for additional uses of these variables.
