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: Fix and enable tracing of msghdr structures.

Useful for sendmsg/recvmsg. However at present it only works for recvmsg,
as sendmsg's parameter is const, and this is not automatically matched.

strace: trace fcntl and wait_for_child syscalls parameters

strace: fix revents output for poll syscall

each poll_fd struct should be checked, valid when not -1 and revents not zero.

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".

* Moved strace sourced to src/bin/debug/.
* Factored a few functions out of strace that can be reused.
* Added the beginnings of a "profile" command. It is very much work in
progress, though it is already able to profile the main thread of a
program.
