Stop using external libaio.h.
This change incorporates a partial copy instead
of using external libaio.h.
Why?
Because we want to properly decode 32-bit aio calls
by 64-bit strace. For that, we need more definitions than
libaio.h provides.
(These defs are not done yet, but will eventually be done).
Keeping our local 32-bit compat defs in sync with libaio.h
_without seeing libaio structs_ is hard/more bug prone.
A smaller benefit is that we don't need libaio installed.

sys_io_submit: simplify iocb_cmd_lookup() helper.
This helper returns two values (a string and an enum).
The caller prints the string. It's simpler to just print
the string in the caller itself. This eliminates
"return by reference" and more importantly, an intermediate
static string buffer for the string result.
Since function of the helper is different now,
it is renamed to tprint_lio_opcode().

Added next_set_bit() function which finds the next set bit,

Use it in decode_select() instead of fd_isset().
Also, properly round fdsize up to word size of traced process,
not to strace's word size.

Fix sigset printing via print_sigset().
Replace print_sigset() with print_sigset_addr_len(),
which takes not only addr, but also len parameter.
This allows us to drop "do we need to print RT signals?" parameter,
and this fixes RT signals printing in many syscalls.
sys_epoll_pwait: print RT signals too, print sigmask size argument.
sys_sigprocmask: print_sigset -> print_sigset_addr_len(current_wordsize),
no change in functionality.
sys_sigpending: use print_sigset_addr_len(current_wordsize)
instead of open-coding it.
sys_rt_sigprocmask: use print_sigset_addr_len instead of open-coding it.
sys_rt_sigpending: ditto.
sys_rt_sigsuspend: ditto.
sys_rt_sigtimedwait: ditto.
do_signalfd: print_sigset -> print_sigset_addr_len. This fixes
RT signals printing (wasn't showing them before).
sys_ppoll: ditto.
copy_sigset_len() is folded into its only user, print_sigset_addr_len(),
and copy_sigset() is gone.
While at it, checked kernel sources and noted where kernel enforces
sigset_size == NSIG / 8 (== sizeof(kernel_sigset_t)),
and where it allows word-sized sigset_size ([rt_]sigpending).

Remove code which supports systems with long long off_t.
While looking at mmap mess, did experimenting in order
to figure out what gets used when.
Tried building armv4tl, armv5l, armv6l, mips, mipsel, i686,
x86_64 and none of they have long long off_t,
which isn't suprprising: we aren't using glibc defines
which enable that.
Moreover, we SHOULD NOT use off_t in syscall decode!
Its size depends on libc, not on arch! I.e. it is essentially
unpredictable and can even in theory vary on the same arch
with different libc.
We should use longs or long longs, in a way which matches
architectural ABI for the given syscall. There are usually
*at most* two permutations, no need to add yet another variable
(sizeof(off_t)) to the mix.
This change removes almost all HAVE_LONG_LONG_OFF_T conditionals,
which will reveal further possible simplifications.
* mem.c: Remove code conditional on HAVE_LONG_LONG_OFF_T.
As a result, never remap sys_mmap64 to sys_mmap.

* io.c (sys_sendfile): Add a FIXME comment.

Cleanup after non-Linux code removal.
Conditions such as defined(LINUX) are always true now,
defined(FREEBSD) etc are always false.
When if directive has them as subexpressions, it can be simplified.
Another trivial changes here are fixes for directive indentation.
