Cleaned up strlib interface
- Replaced some macro calls with the proper interface syntax
- Removed useless macros and workarounds
- Removed no longer needed library function re-definitions
API changes summary:
- The macros remove_control_chars(), trim(), normalize_name(),
stristr(), e_mail_check(), config_switch(), safestrncpy(),
safestrnlen(), safesnprintf(), strline(), bin2hex() can now be safely
used both inside and outside strlib.c
- The macros strnlen() and strtok_r() can now be safely used both
inside and outside strlib.c, on the systems where they are necessary.
The systems that provide those natively, aren't affected by this
change.
- jstrescape() is now strlib->jstrescape()
- jstrescapecpy() is now strlib->jstrescapecpy()
- jmemescapecpy() is now strlib->jmemescapecpy()
- a custom strtoull() implementation is no longer provided, since all
supported systems and compilers provide a library implementation.
