Luis Machado 84c93cd5f1 Fixup testcases outputting own name as a test name and standardize failed compilation messages
Changes in v3:

- Adjusted some testcases where the message "failed to compile" was not unique.

Changes in v2:

- Addressed comments from reviewers.
- Fixed spurious whitespaces.
- Changed compilation failure messages that included source/binary paths to
  ones that are short and deterministic.

---

Another bit of cleanup to the testsuite. We have a number of tests that are
not honoring the rule of not outputting their own name as a test name.

I fixed up all the offenders i could find with the following regular
expression:

"(xfail|kfail|kpass|fail|pass|unsupported|untested) ([A-Za-z0-9]+|\\\$(.)*testfile(.)*)\.exp$"

Pedro Alves 1d2736d43b Fix PR 19494: hang when killing unfollowed fork children
linux_nat_kill relies on get_last_target_status to determine whether
the current inferior is stopped at a unfollowed fork/vfork event.
This is bad because many things can happen ever since we caught the
fork/vfork event...  This commit rewrites that code to instead walk
the thread list looking for unfollowed fork events, similarly to what
was done for remote.c.

New test included.  The main idea of the test is make sure that when
the program stops for a fork catchpoint, and the user kills the
parent, gdb also kills the unfollowed fork child.  Since the child
hasn't been added as an inferior at that point, we need some other
portable way to detect that the child is gone.  The test uses a pipe
for that.  The program forks twice, so you have grandparent, child and
grandchild.  The grandchild inherits the write side of the pipe.  The
grandparent hangs reading from the pipe, since nothing ever writes to
it.  If, when GDB kills the child, it also kills the grandchild, then
the grandparent's pipe read returns 0/EOF and the test passes.
Otherwise, if GDB doesn't kill the grandchild, then the pipe read
never returns and the test times out, like:

 FAIL: gdb.base/catch-fork-kill.exp: fork-kind=fork: exit-kind=kill: fork: kill parent (timeout)
 FAIL: gdb.base/catch-fork-kill.exp: fork-kind=vfork: exit-kind=kill: vfork: kill parent (timeout)

No regressions on x86_64 Fedora 20.  New test passes with gdbserver as
well.
