Bump the glob limits to 512KB for total string size and 64K path
entries. The old limits were too small for some important FTP use cases
like a pkgsrc repository.

Use "unsigned FOO" instead of less-portable "u_FOO".

remove code that did special handling for . and .. at the end of the path.

Instead of changing the code to match the documentation, change the documentation
to match the code. NOCHECK is used only by csh(1) and csh(1) is too broken for
words (histchars quoting is "special").

Do as the man page says, and for GLOB_NOCHECK return the original pattern,
not a modified version with the backslash characters removed.

PR/45517: Henning Petersen: Add restrict keywords in the definition of glob
to match the declaration.

PR/44959: Henning Petersen: glob forgets to closedir on out of space condition.

remove stray printf.

prevent resource DoS from brace expansion (from Maksymilian Arciemowicz)

Add GLOB_STAR support from Greg Dionne.

Apply more limits to GLOB_LIMIT, number of stat(2) calls from me and number
of readdir(3) calls from Maksymilian Arciemowicz. Also reduce the memory
used by matches strings from Maksymilian Arciemowi

add glob_pattern_p for glibc because cvs needs it and it is a huge mess
to compile in the gnu glob code.

Fedora Core 9 doesn't provide ARG_MAX, so use _POSIX_ARG_MAX if it's
not available.

GLOB_NO_DOTDIRS patch from mouse@
Fixes re-definition of GLOB_PERIOD.

Try to fix previous commit of /.. and /. handling for GLOB_PERIOD. I will
write a regression test for this.

Use a separate macro, not DEBUG to enforce 8 bit chars [glob uses internally
16 bit chars]. Fix lint complaint when compiling with 8 bit chars.
