use fchmod(2) instead of chmod(2). it is less racy, and we just opened the descriptor. ok naddy@ stsp@

fix permissions mode bits for fetched pack files; patch by Alisdair MacLeod

handle failed connection attempts to git:// servers; patch by jrick

strip trailing slashes from repository path in got_fetch_parse_uri()

remove redundant leading slashes from repository path when parsing URIs

Stop including <sys/syslimits.h> directly. POSIX says the limits defined there are available from <limits.h>, which almost all affected source files already included anyway. ok millert stsp

use the POSIX standard endian functions and explicitly include <endian.h> ok stsp

do not rely on <zlib.h> to pull in <unistd.h> ok stsp

don't override port configuration with explicit argument if the url doesn't contains it it permits to .ssh/config to be honored same diff from stsp@

stop verifying pack file checksum in the main process during clone/fetch Both got-fetch-pack and got-index-pack now verify the pack file checksum. This means we can avoid reading the entire pack file in the main process just to verify its checksum and avoid a noticable stall between fetching and indexing on slow machines.

represent packfile hash as byte array in the privsep layer, not as object ID

always initialize pack hash output parameter of got_fetch_pack()

add support for fetching arbitrary references to 'got clone' and 'got fetch'

remove GOT_FETCH_DEBUG and toggle fetch debug output with -v option instead

handle reference-only updates in 'got fetch' where server sends an empty pack
