New USES imake to handle the dependency on imake.

This uses accept 'env' as an argument for ports that do use their own or a different do-configure target.

Modify xmkmf so it accept IMAKECPPFLAGS as default flags for imake and pass it to the called imake.
Modify xorg-cf-files (the FreeBSD.cf configuration file) to allow CppCmd to be overwritten.
Pass CppCmd CcCmd and CplusplusCmd via command line to each call of imake via IMAKECPPFLAGS
Pass IMAKE_DEFINE with the above arguments to MAKE_ARGS so that imake spawned from Makefile generated by a previous
imake also inherit the defined CppCmd CcCmd and CplusplusCmd.
Make imake use devel/tradcpp all the time, so that when buidling with clang we do not depend on gcc's cpp.
Make imake respect CC and CXX
Make imake respect USE_GCC (if set imake will use gcc's cpp).

While here:
- Remove a couple of indefinite articles from comments
- Trim headers
- Fix a couple of ports to build with clang or use: USE_GCC=any
- Fix a now useless redefinition of the extraction chain
- Fix a typo in japanese/Wnn7-lib bundled imake template definitions
- Fix some XMKMF execution with no env specified
- Use options helper in x11/xautolock to simplify the port
