1b1577745c regex(3): Add support for \< and \> word delimiters 
Solaris and other OSs have support for \< and \> as word
delimiters in utilities like sed(1). These are useful to
have for general compatiblity with Solaris but should be
avoided for portability with other systems, including the
traditional BSDs.

Bump __FreeBSD_version as this is likely to affect some
userland utilities.

84ca9a6378 Revert r267675: 
The code doesn't really benefit of using reallocf() in this case.
Also, the realloc() results being assigned temporary variable which
makes blind replacement with reallocf() mostly useless.

76a4926d96 regex: Make use of reallocf(). 
Use of reallocf is useful in libraries as we are not certain the
application will exit after NULL.

This somewhat reduces portability but if since you are building
this as part of libc it is likely you have our non-standard
reallocf(3) already.

99c9726a00 Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP} 
if not already defined. This allows building libc from outside of
lib/libc using a reach-over makefile.

A typical use-case is to build a standard ILP32 version and a COMPAT32
version in a single iteration by building the COMPAT32 version using a
reach-over makefile.

0f6ef690b3 Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a 
load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter.  Also
adds support for per-thread locales.  This work was funded by the FreeBSD
Foundation.

Please test any code you have that uses the C standard locale functions!
