Merge branch 'jk/war-on-sprintf'
Many allocations that is manually counted (correctly) that are followed by strcpy/sprintf have been replaced with a less error prone constructs such as xstrfmt. Macintosh-specific breakage was noticed and corrected in this reroll. * jk/war-on-sprintf: (70 commits) name-rev: use strip_suffix to avoid magic numbers use strbuf_complete to conditionally append slash fsck: use for_each_loose_file_in_objdir Makefile: drop D_INO_IN_DIRENT build knob fsck: drop inode-sorting code convert strncpy to memcpy notes: document length of fanout path with a constant color: add color_set helper for copying raw colors prefer memcpy to strcpy help: clean up kfmclient munging receive-pack: simplify keep_arg computation avoid sprintf and strcpy with flex arrays use alloc_ref rather than hand-allocating "struct ref" color: add overflow checks for parsing colors drop strcpy in favor of raw sha1_to_hex use sha1_to_hex_r() instead of strcpy daemon: use cld->env_array when re-spawning stat_tracking_info: convert to argv_array http-push: use an argv_array for setup_revisions fetch-pack: use argv_array for index-pack / unpack-objects ...
