This avoids poking into the filter data structure at various points in
the code. We rely on the fact that the number of arguments is fixed
based on the filter type (set in cgit_new_filter) and that the call
sites all know which filter type they're using.

By switching the assignment of fields in the cgit_filter structure to
use designated initializers, the compiler will initialize all other
fields to their default value. This will be needed when we add the
extra_args field in the next patch.

This is never changed from STDOUT_FILENO, so just use that value
directly.

Now running tests with the "--valgrind" option will run cgit under
Valgrind instead of all Git commands.

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.

It's only used in one place, and not useful to have around since
close_filter will die() if exit_status isn't what it expects, anyway. So
this is best as just a local variable instead of as part of the struct.

* Formatting and spelling fixes.
* A bit mask with the size of one byte only allows for storing 8 (not
255!) different flags.

When parsing command line arguments, no pair of command line options can
ever match simultaneously. Use "else if" blocks to reflect this. This
change improves both readability and speed.

Use suffixcmp() from Git instead of reimplementing it. This is a
preparation for moving to ends_with() in Git 1.8.6.

Use Git string lists instead of str{spn,cspn,ncmp}() magic. This

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.

This is a preparation for replacing all prefix checks with either
strip_prefix() or starts_with() when Git 1.8.6 is released.

* Remove the dependency on Git (which can be obtained automatically when
building, using either the Git submodule or `make get-git`).
* Use proper upstream names of dependencies.

* Several small spelling and capitalization fixes.
* Use consistent and better-looking formatting that is compatible with
AsciiDoc (and partly compatible with RST).
