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.

This patch makes the generated man-page for the filer api section more
similar to the other sections. Also, the bulleted list of environment
variables wasn't rendered correctly (with asciidoc 8.5.2), without an
empty line before the first item.

This patch fixes the following issues:
* the base argument usually isn't zero-terminated, so printing base
without considering baselen will usually generate random garbage
* when the current url represents a directory but doesn't end in a slash,
relative urls would be incorrect
* using unescaped paths allows XSS

No references are kept to the memory pointed to by the 'rel' variable, so
it should be free()'d before returning from add_repo().

The link url wasn't properly escaped, and since the link was identical
to the one used on the commit message it didn't serve any special purpose.

In d0cb841 (Avoid trailing slash in virtual-root), virtual-root was set
from script-name using trim_end(). However, if script-name was the
empty string (""), which happens when cgit is used to serve the root
path on a domain (/), trim_end() returns NULL and cgit acts like
virtual-root is not available. Now, set virtual-root to "" in this
case, which fixes this bug.

When git/date.c:parse_date() cannot parse its input it returns -1. But
read_agefile() checks if the result is different from zero, essentialy
returning random data from the date buffer when parsing fails. This
patch fixes the issue by verifying that the result from parse_date()
is positive.

When calling cgit_print_diff() with a bad new_rev and a NULL old_rev,
checking for new_rev's parent commit will result in a null pointer
dereference. Returning on an invalid commit before dereferencing fixes
this. Spotted with clang-analyzer.

These tests tries to detect bad links in various pages. On the log page,

reencode() takes three arguments in the order (txt, from, to), opposed to
reencode_string, which will, like iconv, handle the arguments with from
and to swapped. Fix that (this makes reencode more intuitive).
If src and dst encoding are equivalent, don't do any encoding.
If no special encoding parameter is found within the commit, assume
UTF-8 and explicitly convert to PAGE_ENCODING. The change to reencode()
mentioned above avoids re-encoding a UTF-8 string to UTF-8, for example.

This patch makes cgit properly abort in case the projectsfile cannot
be opened. Without the added return cgit continues using the projects
pointer which is NULL and thus causes a segfault.
This reintroduces the use of execvp(), since the filter commands doesn't
always contain an absolute path (i.e. snapshot compression filters).

The environment variables can be used to (for example) resolve
the following situation:
Suppose a server setup in which each repository has a trac
instance; the commit filter needs to know with which
repository it's dealing in order to be able to resolve the
#123 ticket numbers in the commit messages into hyperlinks
into the correct trac instance.

Currently the number of extra arguments is linked hard to the type of
the filter. This is also logical since it would be confusing to have
a different number of arguments for the same type of filter depending
on the context under which the filter is run (unless ofcourse one the
parameters would make the context clear, which is currently not the
case).
