For implementing a ui-blame page, there is need for a function that
outputs a selection from a block of text, transformed for HTML output,
but with no further modifications or additions.

Instead of reimplementing URL parameter parsing from scratch, use
url_decode_parameter_name() and url_decode_parameter_value() which are
already provided by Git.
Also, change the return type of http_parse_querystring() to void since
its only caller already ignores the return value.

Sparse complains about this table because we use the integer zero as the
NULL pointer. Use this as an opportunity to reformat the table so that
it always contains 8 elements per row, making it easier to see which
values are being set and which are not.

If we fail to write HTML output once, there's no point carrying on so
just write a failure message once and die. By using Git's die_errno
function we also let the user know in what way the write failed.

This adds the fmtalloc helper, html_txtf, html_vtxtf, and html_attrf.
These takes a printf style format string like htmlf but escapes the
resulting string. The html_vtxtf variant takes a va_list whereas
html_txtf is variadic.

While doing this, remove declarations from header files where the
corresponding definition is declared "static" in order to avoid build
errors.
Also re-order existing headers in ui-*.c so that the file-specific
header always comes immediately after "cgit.h", helping with future
consistency.

This squelches a gcc warning. It's also correct that we check to see if
there are any partial or failed writes. For now, we just print a warning
to stderr. In the future, perhaps it will prove wise to exit(1) on
partial writes.

When a query ends in say %gg, (or any invalid hex) e.g.,
http://git.gnome.org/browse/gdlmm/commit/?id=%gg
convert_query_hexchar calls memmove(txt, txt+3, 0), and then returns
txt-1, so the loop in http_parse_querystring never terminates. The
solution is to make the memmove also copy the trailing NUL.

The source and destination strings in strcpy() may not overlap.
Instead, use memmove(), which allows overlap. This fixes test t0104,

The only valid characters for a URL are unreserved characters
a-zA-Z0-9_-.~ and the reserved characters !*'();:@&=+$,/?%#[] , as per
RFC 3986. Everything else must be escaped. Additionally, the # and
? always have special meaning, and the &, =, and + have special meaning
in a query string, so they too must be escaped. To make this easier,
a table of escapes is now used so that we do not have to call fmt() for
each character; if the entry is 0, no escaping is needed.

None of the html_* functions modify their argument, so they can all be
'const char *' instead of a simple 'char *'. This removes the need to
cast (or copy) when trying to print a const string.

First, an apostrophe is not a quote. Second, we also need to escape
quotes. And finally, quotes are encoded as '"', not '"e;'.

Reset ctx.repo to NULL when the config parser is finished
Move cgit_parse_query() from parsing.c to html.c as http_parse_querystring()
Move function for configfile parsing into configfile.[ch]
Add cache.h
Remove global and obsolete cgit_cmd
Makefile: copy the QUIET constructs from the Makefile in git.git
Move cgit_version from shared.c to cgit.c
Makefile: autobuild dependency rules
Initial Makefile cleanup
Move non-generic functions from shared.c to cgit.c
Add ui-shared.h
Add separate header-files for each page/view
Refactor snapshot support
Add command dispatcher
Remove obsolete cacheitem parameter to ui-functions
Add struct cgit_page to cgit_context
Introduce html.h
Improve initialization of git directory
Move cgit_repo into cgit_context
Add all config variables into struct cgit_context
...
All html-functions can be quite easily separated from the rest of cgit, so
lets do it; the only issue was html_filemode which uses some git-defined
macros so the function is moved into ui-shared.c::cgit_print_filemode().

When a submodule occurs in a tree, generate a link to show the
module/commit. The link is specified as a sprintf string in /etc/cgitrc,
using parameters 'module-link' and 'repo.module-link'. This should probably
be extended with repo.module-link.$path.
