Boost-Build :

I rewrote path.glob again, hopefully it's the last time.

The problem with the previous implementation is that it would iterate
over all elements in a dir even if 'pattern' had no metacharacters. First,
that was slow -- if you handed

/cygdrive/w/My Documents/boost/test/a.cpp

to it, it would crawl all the way to the top, listing each directory and
checking each file. Second, it would fail, because Cygwin is broken and
does not show 'cygdrive' is the list of directory elements of '/'.

The new glob is implemented as new 'GLOB-RECURSIVELY' builtin. I've decided
to use builtin since otherwise, we'd need 'does this name exist' builtin,
and if we need new builtin, why don't implement all globbing in core.

This means you have to rebuild bjam. If you don't, you'll get a nice
error message, explaining that you really have too.

The change is tested on Linux/gcc, nt/borland, and cygwin/gcc.
I would appreciate comments, especially from the persons who had
problems with path.glob on cygwin.
