Timo Sirainen 9296ffbed7 Don't reopen stdio. It's not needed, and it doesn't compile with Solaris.

Timo Sirainen 9cade23616 It's safer to close stdin/out/err by replacing their fd with /dev/null. 
Otherwise the next opened fds are 0/1/2, and any code writing to
stdout/stderr might break things by writing to an unintentional fd.

ST is more correct, but BEL is apparently more widely supported.

Alexander Chernyakhovsky 0099f080ad Fix FTBFS on ARM on GCC 4.7.0 
GCC v4.7.0, as found in Fedora 17 and newer, fails to build mosh on
ARM because of a narrowing warning, which is then promoted to an error
by -Werror.  This error message is new, and did not occur under
previous versions of GCC.

This patch corrects this error by explicitly casting to the desired
datatype the return value of the offending code, the result of a macro
from glibc to implement htobe16().

Dave Taht 72e6c85e3d Set diffserv values to AF42 + ECT 
AF42 has both the properties of CS42 and the IMM bit.

Whether this has the advantages or disadvantages of just one or
the other, I don't know. With most mac80211 stacks this will
force mosh packets in the VI queue on wireless.

As for pfifo_fast, have to look it up...
