Remove the unused repo and private pointers and make the direction a
flag, as it can only have two states. Change the connect signature to
use an int instead of git_net_direction and remove that enum.

These allow you to implement git-ls-remote when given a reference name

Rather than an 'private' pointer, make the private structures inherit
from the generic git_transport struct. This way, we only have to worry
about one memory allocation instead of two. The structures are so
simple that this may even make the code use less memory overall.

Store the ref information in a private struct so we can free it
together with the rest.

By pre-sorting the references, they are already in the right order if
we want to peel them.

With this, we get output-parity with git.git's ls-remote.

This is where they really belong. Remvoe the prefix and make them
static.

This makes it easier to send a requqest for an URL. It assumes there
is a socket where the string should go out to.

Add a parameter to git_pkt_parse_line to tell it how much data you
have in your buffer. If the buffer is too short, it returns an error
saying so. Adapt the git transport to use this and fix the offset
calculation.

Add the GIT_ESHORTBUFFER error code.

A git_pkt object can be one of several structs. Add this function for
convenience and clarity.

A pkt-line's length are described in its first four bytes in ASCII
hex. Copy this substring to another string before feeding it to
git__strtol32. Otherwise, it will read the whole hash.

This are the types I intend to use for pkt-line parsing and (later)
creation. git_pkt serves as a base pointer type and once you know what
type it is you can use the real one (command, tip list, etc.)

If the strings match, git__fnmatch returns GIT_SUCCESS and

MSVC fixes: Added a test for _MSC_VER and (in that case) defined
HAVE_STRING_H to 1 so it doesn't try to include <strings.h> which
doesn't exist in the MSVC world. Moved the function declarations to
use the modern inline ones so MSVC doesn't have a fit. Added casts
everywhere so MSVC doesn't crap its pants.

Move them to their own functions to avoid duplication and to make it
easier to ignore missing configuration.

Not finding 'fetch' is considered fatal, though this might not be
