let callers of got_pack_create() configure rate-limiting of progress reporting Needed by future gotd(8), where progress reports will be sent to a network socket, rather than a local terminal.

move got_opentempfd() call out of got_pack_create() Future gotd(8) needs to run got_pack_create() in a chroot environment, so we can no longer open new temporary files inside got_pack_create(). ok op@

make got_pack_create() write to a file descriptor instead of a stdio FILE The old code required a seekable output file. This conflicts with requirements of future gotd(8), which will write pack file data to network sockets. ok op@

Correctly track if we sent more data since the last time we looked. With the narrow scope of bytes_sent_cur it would always be zero, and we would always update progress. Found by llvm's scan-build (Dead store). OK stsp

print additional progress information while packing ok op@

fix regression where 'got send -T' failed if same tag already exists on server Problem reported and fix tested by Omar Polo.

use RB_TREE instead of STAILQ to manage packindex bloom filters; much faster

make it possible to merge vendor branches with 'got merge'

fix another instance of 'got send' sending branches the server already has

move duplicated dial_ssh() and dial_git() functions into a common file These functions are used by 'got send' and 'got fetch' in order to open network connections to a server. Move them into new file lib/dial.c and declare relevant functions in got_dial.h and lib/got_lib_dial.h. No functional change.

make realloc_ids() malloc-like and do not overallocate Let realloc_ids() take as argument the number of entries to allocate. Do not allocate an extra chunk. ok stsp

drop realloc_ids() initialization calls, one of which had a typo realloc_ids() is called again in the loops that assign to the ID arrays, before the first assignment. ok stsp

do not send a pack file when 'got send' is only deleting branches The git protocol spec says the client MUST NOT send a pack file if the only command used is 'delete'. Fixes 'got send -d' against Github's server which closed the session upon receiving the empty pack file we sent. This problem wasn't caught by regression tests since git-daemon does accept an empty pack file. Problem reported by jrick.

fix the output of 'got send -d' upon success Previous output was: Already up-to-date New output is: Server has deleted refs/heads/branch Check this behavour in the related regression test.

add 'got send' command for sending changes to remote repositories Known to work against git-daemon and github Git server implementations. Tests by abieber, naddy, jrick, and myself. Man page additions reviewed by Lucas.
