Quota support for Cygwin

[rb07]

This change, needed to build under Cygwin(*), got lost somehow:

Cygwin added the <sys/quota.h> missing header after Transmission 2.82 was released (i.e. it didn't build before w/o manually adding the header), but its now present.

(*) Not the only change needed. Also "-ansi" needs to be deleted on third-party/libutp/Makefile (reported long ago to them).

Damn, commit message is not correct. I should sleep more I guess.
