Merge branch 'jk/config-use-size-t'

The config API made mixed uses of int and size_t types to represent
length of various pieces of text it parsed, which has been updated
to use the correct type (i.e. size_t) throughout.

* jk/config-use-size-t:
  config: reject parsing of files over INT_MAX
  config: use size_t to store parsed variable baselen
  git_config_parse_key(): return baselen as size_t
  config: drop useless length variable in write_pair()
  parse_config_key(): return subsection len as size_t
  remote: drop auto-strlen behavior of make_branch() and make_rewrite()
