  finish_connect(): thinkofix
  git-mv: succeed even if source is a prefix of destination
  Solaris does not support C99 format strings before version 10

All but one callers have ignore the return value from this
function, but the only caller, builtin-tar-tree.c::remote_tar(),
assumed it returns non-zero on failure and zero on success.  The
implementation however was returning either the waited pid
(which must be the same as its input) or -1 (an error).

Fix this thinko, while getting rid of an assignment of return
value from waitpid() into a variable of type int.

This cleans up the implementation of "git-apply --binary", and
implements reverse application of binary patches (when git-diff
is converted to emit reversible binary patches).

Earlier, the types of encoding (either deflated literal or
deflated delta) were stored in is_binary field in struct patch,
which meant that we cannot store more than one fragment that
differ in the encoding for a patch.  This moves the information
to a field in struct fragment that is otherwise unused for
binary patches, and makes it possible to hang two (or more, but
two is enough) hunks for a binary patch.

The original "binary patch" output from git-diff is internally
parsed into an "is_binary" patch with one fragment.  Upcoming
reversible binary patch output will have two fragments, the
first one being the forward patch and the second one the reverse
patch.

On Solaris and the BSDs the definition of "struct sockaddr_storage"
is not available from "netinet/in.h".  On Solaris "sys/socket.h" is
enough, at least OpenBSD needs "sys/types.h", too.

Using "sys/types.h" and "sys/socket.h" seems to be a more portable
way.

I've always found difficult to figure out git URL for clone from
gitweb URL because git:// and http:// are different on many site
including kernel.org.

I've found this enhancement at http://dev.laptop.org/git when I was on
git channel, and thought that it'd be nice if all public gitweb site
show it's git URL on its page.

This patch allow us to change the home link string.  The current
default is "projects" as we all see on gitweb now.

ie. kernel.org might set this variable to "git://git.kernel.org/pub/scm/"

Change git_get_references to include type of ref in the %refs value, which
means putting everything after 'refs/' as a ref name, not only last
part of the name.  Instead of separating refs pointing to the same
object by " / " separator, use anonymous array reference to store all
refs pointing to given object.

Use 'git-ls-remote .' if $projectroot/$project/info/refs does not
exist.  (Perhaps it should be used always.)

Refs are now in separate span elements.  Class is dependent on the ref
type: currently known classes are 'tag', 'head', 'remote', and 'ref'
(last one for HEAD and other refs in the main directory).  There is
encompassing span element of class refs, just in case of unknown ref
type.

This might be considered cleaner separating of git_get_references into
filling %refs hash only, and not taking part in formatting ref marker.

Rename some of subroutines to better reflect what they do.
Some renames were not performed because subroutine name
reflects hash key.

Subroutines name guideline:
* git_ prefix for subroutines related to git commands,
  git repository, or to gitweb actions
* git_get_ prefix for inner subroutines calling git command
  or reading some file in the repository and returning some output
* parse_ prefix for subroutines parsing some text (or reading and
  parsing some text) into hash or list
* format_ prefix for subroutines formatting, post-processing
  or generating some HTML/text fragment
* _get_ infix for subroutines which return result
* _print_ infix for subroutines which print fragment of output
* _body suffix for subroutines which outputs main part (body)
  of related action (usually table)
* _nav suffix for subroutines related to navigation bars
* _div suffix for subroutines returning or printing div element
* subroutine names should not be based on how the result is obtained,
  as this might change easily

Renames performed:
- git_get_referencing => format_ref_marker
- git_get_paging_nav => format_paging_nav
- git_read_head => git_get_head_hash
- git_read_hash => git_get_hash_by_ref
