This commit does most of the mechanical removal. IOW, the easy part.
procfs.c isn't touched beyond removing a couple obvious bits that are
guarded by a couple macros defined in config/alpha/nm-osf3.h. Going
beyond that for procfs.c & co would be a harder excision that
potentially affects Solaris.
Some comments in the generic alpha code ABIs that may still be
relevant and I wouldn't know what to do with them. That can always be
done on a separate pass, preferably by someone who can test on alpha.
A couple other spots have references to OSF/Tru64 and related files
being removed, but it felt like removing them would make things worse,
not better. We can revisit those when we next need to touch that
code.
I didn't remove a reference to osf in testsuite/lib/future.exp, as I
believe that code is imported from DejaGNU.
Built and tested on x86_64 Fedora 20, with --enable-targets=all.
Tested that building for --target=alpha-osf3 on x86_64 Fedora 20

* gdb.texinfo (Ada Tasks and Core Files): Delete mention of Tru64.
(SVR4 Process Information): Delete mention of OSF/1.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
* gdb.threads/pthreads.exp (check_control_c): Return 0 for success,
non-zero if control_c fails. Terminate the test on failure,
rather than wait for 12 more tests to time out.
* gdb.threads/pthreads.exp (all_threads_running): Add an explicit
test for (full_coverage == 0). This makes the test run faster,
and prevents dejagnu getting out of step.
Change to rely on PIDGET etc.

TARGET_CAN_USE_HARDWARE_WATCHPOINT, HAVE_CONTINUABLE_WATCHPOINT,
STOPPED_BY_WATCHPOINT, target_[insert/remove]_watchpoint):
define. Allow target to use procfs hardware watchpoints.

definitions to use 16 bits for the pid, 15 bits for the tid, and
1 bit for the flag.

(SOFTWARE_SINGLE_STEP, SOFTWARE_SINGLE_STEP_P): undefine.
* testsuite/gdb.threads/pthreads.exp (all_threads_running): Allow
for more than 15 thread increments.
