Instead of using our own formatting, use log_tree_commit() from Git to
create patches. This removes unnecessary duplicate code and also fixes a
bug with e-mail address formatting that existed in our own
implementation.

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.

Move filepair_cb() from ui-patch.c to ui-shared.c and rename it to
filepair_cb_raw(). This callback will be used in ui-diff.c in a
follow-up patch.
Note that it is not straightforward to extract filepair_cb() from
ui-diff.c which is why it is not done here as well.

When having found the first path separator occurrence at position i, we
invoked strchr() on the same position i in subsequent iterations
resulting in the same path separator being returned by strchr() over and
over again. Increase the position by one to skip the occurrence that has
just been found and advance to the next separator.

Use struct strbuf from Git instead of fixed-size buffers to remove the

read_config_line() to improve readability.

In cgit_print_snapshot_links() we strip leading "v" and "V", while we
currently only prepend a lower case "v" when parsing a snapshot file
name. This results in broken snapshot links for tags that start with an
upper case "V". Avoid this by prepending a "V" as a fallback.

getenv() returns a NULL pointer if the specified variable name cannot be
found in the environment. However, some setenv() implementations crash
if a NULL pointer is passed as second argument. Only restore variables
that are not NULL.

print_tag_header() is only called from cgit_print_tags() -- the
conditional invocation in print_tag() is never executed since
print_tag() is only called by cgit_print_tags() which already executes
print_tag_header() before (resulting in the global variable being always
set in when the condition is evaluated).
Remove the global variable and the conditional invocation.

The return values of these functions are essentially constant and should
never be modified.
Note that this will introduce a compiler warning when we try to free the
return value of any of these functions. However, given that all of these
currently return statically allocated strings in some cases, they need
to be refactored before this can be done anyway.

There's no need for this variable to be global. Printing the header in
print_urls() instead of print_url() allows for moving this variable into
print_urls() without having to pass any status to print_url().

than once.

Some setenv() implementations (e.g. the one in OpenBSD's stdlib)
segfault if we pass a NULL value. Only set environment variables if the
corresponding settings are defined to avoid this.
Note that this is a minor behaviour change as environment variables were
supposed to be set to an empty string if a setting was undefined. Given
that this feature isn't part of any official release yet, there's no
need to worry about backwards compatibility, really. Change the
documentation accordingly.
