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.

800380dde7 filter: return on null filter from open and close
So that we don't have to include the if(filter) open_filter(filter)
block everywhere, we introduce the guard in the function itself. This
should simplify quite a bit of code.

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.

This avoids poking into the filter data structure at various points in

based on the filter type (set in cgit_new_filter) and that the call
sites all know which filter type they're using.

382ecf152e cache: don't leave cache_slot fields uninitialized
Valgrind says:

==18344== Conditional jump or move depends on uninitialised value(s)
==18344==    at 0x406C83: open_slot (cache.c:63)
==18344==    by 0x407478: cache_ls (cache.c:403)
==18344==    by 0x404C9A: process_request (cgit.c:639)
==18344==    by 0x406BD2: fill_slot (cache.c:190)
==18344==    by 0x4071A0: cache_process (cache.c:284)
==18344==    by 0x404461: main (cgit.c:952)
==18344==  Uninitialised value was created by a stack allocation
==18344==    at 0x40738B: cache_ls (cache.c:375)

This is caused by the keylen field being used to calculate whether or
not a slot is matched.  We never then check the value of this and the
length of data read depends on the key length read from the file so this
isn't dangerous, but it's nice to avoid branching based on uninitialized
data.

2abce4300b Disallow use of undocumented snapshot delimiters
Since the introduction of selective snapshot format configuration in
dc3c9b5 (allow selective enabling of snapshots, 2007-07-21), we allowed
seven different delimiters for snapshot formats, while the documentation
has always been clear about spaces being the only valid delimiter:

    The value is a space-separated list of zero or more of the values
    "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".

Supporting the undocumented delimiters makes the code unnecessarily
complex. Remove them.

4468ec1b15 Reduce line number bloat, fix hover effect
Currently line numbers look like (for blob view and sdiff respectively):

    <a class='no' id='n68' name='n68' href='#n68'>68</a>
    <td class='lineno'><a class='no' href='...#n1' id='n1' name='n1'>1</a></td>

name=".." is unnecessary if the id attribute is set (this even applies
to IE6), so drop it. (aside, in HTML5, the name attribute is gone.)

The line number links can be selected through their parent classes, no
need for another class "no", so drop it too.

For a file with 2000 lines, this yields a saving of 40% (29% gzipped).

While at it, fix the hover effect of line numbers: now the line number
get a black background as was intended.

We don't want a charset when we have selected "application/octet-stream"

specified their own charset.  To avoid this, make sure we set the page's
