This is the last and final patch to fix the DJGPP port. The only difference
compared with the initial patch is that it checks mow all file names for LFN
validity. The dirname part and the basename part of the file name are now
checked for ilicit initial dots in the case that no LFN support is provided
by the file system. I have attached the patch as gzip'ed file too.
Similar patches are also provided for the openssl 1.0.1 branch and the
openssl 1.0.2 branch too.

Juan M. Guerrero

* Configure: Replaced -DTERMIO by -DTERMIOS in CFLAGS.
* crypto/bio/bss_dgram.c [WATT32]: Remove obsolete redefinition of
function names: sock_write, sock_read and sock_puts.
* crypto/bio/bss_sock.c [WATT32]: For Watt-32 2.2.11 sock_write,
sock_read and sock_puts are redefined to their private names so their
names must be undefined first before they can be redefined again.
* crypto/bio/bss_file.c (file_fopen) [OPENSSL_SYS_MSDOS]: Call
dosify_filename to replace leading dot if file system does not support
it.
(dosify_filename): Replace leading dot in passed file name if file
system does not support LFN. Replace all leading dots in the dirname
part and the basname part of the file name.
* e_os.h [__DJGPP__]: Undefine macro DEVRANDOM_EGD. Neither MS-DOS
nor FreeDOS provide 'egd' sockets.
New macro HAS_LFN_SUPPORT checks if underlying file system supports
long file names or not.
Include sys/un.h.
Define WATT32_NO_OLDIES.
* INSTALL.DJGPP: Update URL of WATT-32 library.
