Use the xstrdup() wrapper which already bails out if strdup() returns a
NULL pointer.

8f20879431 Always #include corresponding .h in .c files
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.

6d7e3596eb html: check return value of write
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.

This fixes a segfault for me with with -O2 optimization on x86

fc384b16fb do not infloop on a query ending in %XY, for invalid hex X or Y
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.
* html.c (convert_query_hexchar): Fix off-by-one error.

a2c6355f9f html: properly percent-escape URLs
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.

25105d7eca Add caching infrastructure
This enables internal caching of page output.

Page requests are split into four groups:
  1) repo listing (front page)
  2) repo summary
  3) repo pages w/symbolic references in query string
  4) repo pages w/constant sha1's in query string

Each group has a TTL specified in minutes. When a page is requested, a cached
filename is stat(2)'ed and st_mtime is compared to time(2). If TTL has expired
(or the file didn't exist), the cached file is regenerated.

When generating a cached file, locking is used to avoid parallell processing
of the request. If multiple processes tries to aquire the same lock, the ones
who fail to get the lock serves the (expired) cached file. If the cached file
don't exist, the process instead calls sched_yield(2) before restarting the
request processing.
