Cygwin: config.h: stop including auto-generated tlsoffsets.h file
This was a hack to begin with. Clean this mess up:
- Move definition of CYGTLS_PADSIZE to cygwin/config.h and drop
local cygtls_padsize.h
- Rename CYGTLS_PADSIZE to __CYGTLS_PADSIZE__ to keep namespace
clean. Redefine as macro, rather than as const.
- Move struct _reent first in struct _cygtls to allow using
__CYGTLS_PADSIZE__ as offset in __getreent().
