strace: Add mutex type

Added a dedicated mutex type handler that can print mutex status
flags while still showing the mutex address.

strace: Improvements

- Added some utility functions to the `Context` class.
- Updated the `sockaddr` handler to retrieve the next sibling
rather than the sibling at index 2. This allows the handler to
work for syscalls where the `socklen_t` argument is not the third
one, for example, `_kern_recvfrom`.
- Added the ability to print the `flatArgs` for `_kern_exec` and
`_kern_load_image`.

strace: Print detailed signal information

- Add support for retrieving the `siginfo_t` structure of a signal
event from the Debugger API.
- Add code to `strace` to display this information every time a
signal event occurs, similar to the Linux `strace` tool.

strace: Fix names of hardcoded syscall lists.

Before this commit, specifying %memory or %network just crashed strace.
I guess this was never tested?

strace: Trivial improvements.

* Break in FlagsTypeHandler once we have cleared all flags.
* Use sizeof(hex) instead of writing out the size again.
* Place comment above variable name in patch_syscalls.

strace: Create a status_t type handler and use it for return values.

This way, we save 3 string comparisons on every non-empty return value.

Actually this code was broken before, and did not print error names
for return types other than status_t, because message.return_value
is an unsigned integer and thus "< 0" was always false. Now we cast
appropriately in the new TypeHandler, so this works properly.

strace: Do not print unnecessary parentheses.

Cleans up output somewhat.

strace: Add area protection flags printing.

Using the new FlagsTypeHandler.

strace: shows values for create_pipe and socketpair.

strace: handle parallel syscalls on different threads

If a thread executes a system call and meanwhile a different thread calls another one, then
the ongoing call is marked as unfinished. When the call returns it will be marked as resumed.

* remove PreSyscall, now unused.

strace: support trace for poll() and select()

in the case of poll(), the events should be printed before the actual syscall,
and the revents after, while taking in account the return value.
thus B_DEBUGGER_MESSAGE_PRE_SYSCALL needs to be enabled and handled.
the attribute "preSyscall" is added to identify such syscalls, and the parameters
are identified with the attribute "inOut".

strace: Gracefully handle invalid syscall numbers.

OpenJDK 1.8 somehow manages to trigger this. Before this commit it would
just attempt to read past the end of the vector, which of course segfaulted,
which seems to imply nobody has run into this case before.

strace: Added option to dump syscall stats.

* Use -c/-C (same as in Linux's strace) to enable the stat output.
* Former -c to turn of colored output is now --no-color.

include strings.h where appriopriate...

instead or additionally to string.h, in preparation for functions move.
* moves str[n]casecmp() functions and others to strings.h.
* strings.h doesn't include string.h anymore.
* this solves #10949

Adjust debug_utils functions.

The functions in question now return an error rather than simply calling
exit() directly when they fail, as this behavior wasn't acceptable for
e.g. Debugger. Adjusted all calling apps accordingly.

x86_64 support for GDB.

As mentioned in one of the previous commits, breakpoints don't work
properly yet, and I haven't done much extensive testing yet, but the
basic functionality works.

Merged signals-merge branch into trunk with the following changes:
* Reorganized the kernel locking related to threads and teams.
* We now discriminate correctly between process and thread signals. Signal
handlers have been moved to teams. Fixes #5679.
* Implemented real-time signal support, including signal queuing, SA_SIGINFO
support, sigqueue(), sigwaitinfo(), sigtimedwait(), waitid(), and the addition
of the real-time signal range. Closes #1935 and #2695.
* Gave SIGBUS a separate signal number. Fixes #6704.
* Implemented <time.h> clock and timer support, and fixed/completed alarm() and
[set]itimer(). Closes #5682.
* Implemented support for thread cancellation. Closes #5686.
* Moved send_signal() from <signal.h> to <OS.h>. Fixes #7554.
* Lots over smaller more or less related changes.
