Merge branch 'ph/strbuf'
* ph/strbuf: (44 commits) Make read_patch_file work on a strbuf. strbuf_read_file enhancement, and use it. strbuf change: be sure ->buf is never ever NULL. double free in builtin-update-index.c Clean up stripspace a bit, use strbuf even more. Add strbuf_read_file(). rerere: Fix use of an empty strbuf.buf Small cache_tree_write refactor. Make builtin-rerere use of strbuf nicer and more efficient. Add strbuf_cmp. strbuf_setlen(): do not barf on setting length of an empty buffer to 0 sq_quote_argv and add_to_string rework with strbuf's. Full rework of quote_c_style and write_name_quoted. Rework unquote_c_style to work on a strbuf. strbuf API additions and enhancements. nfv?asprintf are broken without va_copy, workaround them. Fix the expansion pattern of the pseudo-static path buffer. builtin-for-each-ref.c::copy_name() - do not overstep the buffer. builtin-apply.c: fix a tiny leak introduced during xmemdupz() conversion. Use xmemdupz() in many places. ...
