[PATCH 0/3] strbuf.[ch]: add STRBUF_HINT_SIZE, don't hardcode 8192

A rather trivial cleanup series to avoid hardcoding 8192 in N places in strbuf.[ch], instead we add a STRBUF_HINT_SIZE macro. Then make strbuf_fread() take a "hint" instead of "size" (like most similar functions) so we can pass a size of "0" meaning the default hint to it.

Ævar Arnfjörð Bjarmason (3):
  strbuf.[ch]: add STRBUF_HINT_SIZE macro = 8192
  strbuf.h API users: don't hardcode 8192, use STRBUF_HINT_SIZE
  strbuf.[ch]: make strbuf_fread() take hint, not size
