c3e0509275 Fix the build on NetBSD/OpenBSD/FreeBSD, possibly others.
Various termios flags used in sp_open() are Linux-specific (or even
specific to certain architectures / drivers) and not available on all
OSes (and/or versions or kernels thereof).

Thus, #ifdef out flags that we know might not be available everywhere.

71c8a9b906 serialport.c: Add missing linux_termios.h #include.
This is safe to include (at the moment) on all non-win32 OSes, since it
doesn't contain anything OS-specific.

Thanks to Dan Horák for the report.

1d5d2a166f Temporarily disable USE_TERMIOX code (breaks the lib).
On some systems the use of the code enabled by USE_TERMIOX leads to a
non-working sp_open() which breaks all functionality provided by the lib.

Thus, temporarily disable that code until the details are investigated.

This has been tested with a serial port DMM and the OLS logic analyzer
on an x86 64bit Linux system with kernel version 3.11. The code compiles
fine but doesn't work at runtime. The configure output included:

checking for struct termios2... yes
checking for struct termiox... yes

The root cause for the problem is that the ioctl(fd, TCGETX, data) call in
get_flow() returns -1 ("Invalid argument"), which in turn lets sp_open()
return SP_ERR_FAIL.
