7e1c0ed2aa diffstat: do not rely on uninitialized data
Right now if you visit:
<http://git.zx2c4.com/systemd/diff/src/udev/udev-builtin-input_id.c?id=bcfce235>
you'll see that if you reload the page a few times, a bunch of times the
diffstat comes out with no lines being shown or changed. I'm not
currently sure what the cause of this is, but I suspect it might have to
do with this uninitialized data.

e8cacb5981 gen-version.sh: check if git is available before trying to call it
Some people may clone the cgit repository and compile within a sandbox
or on another machine where git is not necessarily installed. When it
happens, cgit is getting compiled with an empty version number.

This commit fixes this.

d3581b5889 cache: use sendfile() instead of a pair of read() + write()
sendfile() does the same job and avoids to copy the content into userland
and back. One has to define NO_SENDFILE in case the OS (kernel / libc)
does not supported. It is disabled by default on non-linux environemnts.
According to the glibc, sendfile64() was added in Linux 2.4 (so it has
been there for a while) but after browsing over the mapage of FreeBSD's I
noticed that the prototype is little different.

* cgit_print_http_headers()
* cgit_print_docstart()
* cgit_print_pageheader()

Remove context parameter from all commands

Drop the context parameter from the following functions (and all static

* cgit_get_cmd()
* All cgit command functions.
* cgit_clone_info()
* cgit_clone_objects()
* cgit_clone_head()
* cgit_print_plain()
* cgit_show_stats()

In initialization routines, use the global context variable instead of
passing a pointer around locally.

Remove callback data parameter for cache slots

This is no longer needed since the context is always read from the
global context variable.

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.

3488d12405 makefile: auto-detect presence of various Lua, bsd
We favor LuaJIT over Lua. We disable Lua if neither can be found. We
error out if a particular Lua is specified via LUA_IMPLEMENTATION=JIT or
LUA_IMPLEMENTATION=VANILLA, but cannot be found. We print a status
message depending on what happens.

Also, we do not link against libdl on the BSDs, since they include it as
part of libc.

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().

7bd90b8048 filter: add interface layer
Change the existing cgit_{open,close,fprintf}_filter functions to
delegate to filter-specific implementations accessed via function
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.

ceffeb5d52 filters: Improved syntax-highlighting.py
- Switched back to python2 according to a problem in pygments with python3.
  With the next release of pygments this problem should be fixed.
  Issue see here:
  https://bitbucket.org/birkenfeld/pygments-main/issue/901/problems-with-python3
- Just read the stdin, decode it to utf-8 and ignore unknown signs. This ensures
  that even destroyed files do not cause any errors in the filter.
- Improved language guessing:
  -> At first use guess_lexer_for_filename for a better detection of the used
     programming languages (even mixed cases will be detected, e.g. php + html).
  -> If nothing was found look if there is a shebang and use guess_lexer.
  -> As default/fallback choose TextLexer.
