Adjust timing parameters to reduce overall elapsed time, and document
the parameters.
Clean-up status handling for kevent test.
Deal with QEMU timer-related issues (PR-43997).
the TLS pointer, therefore wrecking the pthread environement.
Some ports had _UC_TLSBASE flag or equivalent (_UC_UNIQUE on alpha)
that controlled whether setcontext() would change the TLS pointer.
This change let libpthread override setcontext() with its own version
that unsets _UC_TLSBASE, enabling safe usage of setcontext() with
-lpthread.
We also have the following required changes here:
- rename alpha's _UC_UNIQUE into _UC_TLSBASE
- add _UC_TLSBASE definition in header file for all ports
(powerpc, sh3, sparc and sparc64 lack the implementation for now)
- introduce a libc stub that can be overriden for setcontext()
- modify MD libcs swapcontext() implementations so that they use the
setcontext() libc stub instead of doing a plain system call.
While we are there:
- document various MD _UC_* flags in header file
- add libc and libpthread tests for swapcontext() behavior
(hopefully helpful to spot MD problems introduced with this change)
Future work:
- Deciding whether kernel support or _UC_TLSBASE should be added for
powerpc, sh3, sparc and sparc64 is left to portmasters

- Merge h_regex_att (att.c) and t_regex_att.sh into a single C test program.
The former was really a test program, and the latter just a very strange
driver for it.
- Stop using awk to generate the shell test programs. This is unnecessary
and confusing. Instead, change t_regex.sh to generate the test case
functions on the fly with eval (as done in many other places).
limits (often way too high) and skipping the test case if in doubt,
raise the limits as far as we can, and fix a few places in the test where
we could run into the limits and either skip or fail with a reasonable
message.
