Code clean-up.
* jk/snprintf-cleanups:
daemon: use an argv_array to exec children
gc: replace local buffer with git_path
transport-helper: replace checked snprintf with xsnprintf
convert unchecked snprintf into xsnprintf
combine-diff: replace malloc/snprintf with xstrfmt
replace unchecked snprintf calls with heap buffers
receive-pack: print --pack-header directly into argv array
name-rev: replace static buffer with strbuf
create_branch: use xstrfmt for reflog message
create_branch: move msg setup closer to point of use
avoid using mksnpath for refs
avoid using fixed PATH_MAX buffers for refs
fetch: use heap buffer to format reflog
tag: use strbuf to format tag header
diff: avoid fixed-size buffer for patch-ids
odb_mkstemp: use git_path_buf
odb_mkstemp: write filename into strbuf
do not check odb_mkstemp return value for errors
