A return value of `len` or more means that the output was truncated.

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.

This fixes a segfault for me with with -O2 optimization on x86
with gcc (Debian 4.4.5-8) 4.4.5
I can reliably reproduce it with the following parameters
when pointed to the git.git repository:
PATH_INFO='/git-core.git/diff/'
QUERY_STRING='id=2b93bfac0f5bcabbf60f174f4e7bfa9e318e64d5&id2=d6da71a9d16b8cf27f9d8f90692d3625c849cbc8'

Ampersands ("&") appearing inside HTML attributes need to be translated
to "&". Otherwise, invalid XHTML will be generated at various
places, such as at tree views containing links to submodules.

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.

The source and destination strings in strcpy() may not overlap.
Instead, use memmove(), which allows overlap. This fixes test t0104,
where 'url=foo%2bbar/tree' was being parsed improperly.

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;'.

Normally when html_include cannot open the file it fails silently and
things can be a bit hard to figure out from just looking at apache's

with cgit.

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.
