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 privsep code from pack_create.c into new file pack_create_privsep.c
Needed by future gotd(8). ok op@
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@
simplify the way 'got patch' opens a tempfile when reading from stdin
Also add basic test coverage for reading patches from stdin, while here. ok op@
