Jeff Smith 70787254b2 html: html_ntxt with no ellipsis
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.

Lukas Fleischer 927b0ae30c Simplify http_parse_querystring()
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.

John Keeping 438bac6f57 html: avoid using a plain integer as a NULL pointer
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.

John Keeping 1fec7cd6f8 html.c: die when write fails
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.

John Keeping 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.

Jason A. Donenfeld 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.

Jim Meyering 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.

Mark Lodato 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.
