Subject: * cygtls.cc (_cygtls::call): Call call2 using _my_tls.
 (_cygtls::init_exception_handler): Always replace existing exception handler
 with cygwin exception handler. * cygtls.h (_cygtls::call2): Remove static
 designation. * dcrto.cc (dll_crt0_1): Define in a way that allows calling via
 _cygtls::call. (_initialize_main_tls): Delete. (_dll_crt0): Call dll_crt0_1
 via cygtls::call.  Set _main_tls here. * external.cc (cygwin_internal):
 Implement CW_CYGTLS_PADSIZE. * include/sys/cygwin.h (CW_CYGTLS_PADSIZE):
 Define. * tlsoffsets.h: Regenerate.
