Jeff Hostetler 77e522caae unix-socket: disallow chdir() when creating unix domain sockets
Calls to `chdir()` are dangerous in a multi-threaded context.  If
`unix_stream_listen()` or `unix_stream_connect()` is given a socket
pathname that is too long to fit in a `sockaddr_un` structure, it will
`chdir()` to the parent directory of the requested socket pathname,
create the socket using a relative pathname, and then `chdir()` back.
This is not thread-safe.

Teach `unix_sockaddr_init()` to not allow calls to `chdir()` when this
flag is set.

Jeff Hostetler 55144ccb0a unix-socket: add backlog size option to unix_stream_listen()
Update `unix_stream_listen()` to take an options structure to override
default behaviors.  This commit includes the size of the `listen()` backlog.

Jeff King e2770979fe credentials: add "cache" helper
If you access repositories over smart-http using http
authentication, then it can be annoying to have git ask you
for your password repeatedly. We cache credentials in
memory, of course, but git is composed of many small
programs. Having to input your password for each one can be
frustrating.

This patch introduces a credential helper that will cache
passwords in memory for a short period of time.
