Add some missing #includes, termcap.c, hopefully fixing Adam Sjoegren's build.
2010-09-18 Aidan Kehoe <kehoea@parhasard.net>
* termcap.c:
Add a couple of missing includes here, which should fix builds
that use this file. (I have no access to such builds, but Mats'
buildbot shows output that indicates they fail at link time since
DEVICE_BAUD_RATE and IS_DIRECTORY_SEP are available.)
