Sync with what we do everywhere else and check the return value of
get_sha1() instead of calling sha1_object_info() to validate the object.
Note that we later call lookup_commit_reference(), which checks that
both SHA1 values refer to commits, anyway.

This removes many uses of "fmt" which uses a fixed size static pool of
fixed size buffers. Instead of relying on these, we now pass around
argument lists for as long as possible before using a strbuf to render
content of an arbitrary size.

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.

Copying the output of cgit and using it in patches now works when adding
files to or removing files from the repository. This is helpful for people
who use cgit in their patch workflow.
When side-by-side-diffs=1 was set in cgitrc, specifying 'ss=0' in the
querystring would not set the 'unified' option as active in the dropdown
box used to select diffmode.
When side-by-side-diffs=1 was set in cgitrc, specyfing 'ss=0' in the query-
string would not switch to unified diffs. This patch fixes the issue by
introducing a separate variable to track the occurrence of "ss" in the
querystring.
The file name displayed in the rename hint should be escaped to avoid
XSS. Note that this vulnerability is only applicable when an attacker
has gained push access to the repository.

When calling cgit_print_diff() with a bad new_rev and a NULL old_rev,
checking for new_rev's parent commit will result in a null pointer
dereference. Returning on an invalid commit before dereferencing fixes
this. Spotted with clang-analyzer.

There were many places where the arguments to a printf-like function did
not match the format string. Mostly, these were a missing 'l' flag, but
there were three exceptions:
- In ui-stats.c, a size_t argument must be printed. C99 has the "%zu"
flag for this purpose, but not all compilers support this. Therefore,
we mimic what git does - use a NO_C99_FORMAT Makefile variable.
- In ui-stats.c, cgit_print_error() was called with a pointer instead of
a character.
- In ui-log.c, the "columns" argument was never used.

Add a link to the "Diffstat" line to ignore/show whitespace changes in the

To support this, cgit_commit_link() and cgit_diff_link() has learned to

The links in the diffstat is supposed to work as a filter for the diff,
but this only worked when a single rev was supplied, i.e. the filtered
diff was always against the parent of the specified rev.
With this patch it is now possible to use the diffstat as a 'filter menu'
for urls like http://hjemli.net/git/cgit/diff/?id=v0.7.2&id2=v0.7.1

This adds a new function used to generate links to the diff page and uses
it everywhere such links appear (expect for single files in the diffstat
displayed on the commit page: this is now a link to the tree page).
The updated diff-page now expects zero, one or two revision specifiers, in
parameters head, id and id2. Id defaults to head unless otherwise specified,
while head (as usual) defaults to repo.defbranch. If id2 isn't specified, it
defaults to the first parent of id1.
The most important change is of course that now all repo pages (summary, log,
tree, commit and diff) has support for passing on the current branch and
revision, i.e. the road is now open for a 'static' menu with links to all
of these pages.
