Replace valid memory checks with new myfault class "exception handling", almost
everywhere. Leave some thread.cc stuff alone for now. * cygtls.h: Kludge some definitions to avoid including a problematic windows header. (_cygtls::_myfault): New entry. (_cygtls::_myfault_errno): Ditto. (_cygtls::fault_guarded): New function. (_cygtls::setup_fault): Ditto. (_cygtls::return_from_fault): Ditto. (_cygtls::clear_fault): Ditto. (myfault): New class. * exceptions.cc (handle_exceptions): Handle case of guarded fault in system routine. * gendef: Add another entry point for setjmp that the compiler doesn't know about and won't complain about. * gentls_offsets: Just include windows.h rather than kludging a HANDLE def. * miscfuncs.cc (check_null_str): Delete. (check_null_empty_str): Ditto. (check_null_empty_str_errno): Ditto. (check_null_str_errno): Ditto. (__check_null_invalid_struct): Ditto. (__check_null_invalid_struct_errno): Ditto. (__check_invalid_read_ptr): Ditto. (__check_invalid_read_ptr_errno): Ditto. (dummytest): New function. (check_iovec_for_read): Delete. (chec_iovec): Rename from check_iovec_for_write. Take a read/write parameter. * tlsoffsets.h: Regenerate. * winsup.h: Remove check_* declarations. (check_iovec_for_read): Delete declaration. Turn into a define instead. (check_iovec_for_write): Ditto. (check_iovec): New declaration. * thread.h: Use ifdef guard name consistent with other header files.
