Update to 1.43.  Claim maintainership.

Changes since 1.41:
- fix to avoid modifying data which is being used by tsearch() for
  ordering the binary tree (report by Adrian Bunk).
- do not ignore pathnames in /tmp/, since some tools create usable
  pathnames for both old/new files there (Debian #376086).
- correct ifdef for fgetc_unlocked().
- updated configure macros CF_GCC_VERSION, CF_PATH_SYNTAX and
  CF_XOPEN_SOURCE
- add configure check for compress, gzip and bzip2 programs that may be
  used to decompress files.
