259ecb3d11 ps: Select specific processes by their PIDs
This adds a `-q` option, which expects a comma-separated list of PIDs as
a value. On using it, only the processes associated with the supplied
PIDs are output.

e36931fffe Utilities: Add a command line client for ConfigServer
This is an alternative to the ini utility which accesses the
configuration files through the newly introduced ConfigServer.

2dea772d48 shot: Get only cropped region from WindowServer
Previously, we were always getting the full screen(s) bitmap from
the WindowServer and cropping it manually. The `get_screen_bitmap`
function already took in a `crop_region`, so we are now utilizing
that.

7d7d310df6 Base+Utilities: Add the asctl audio utility, replacing avol
The new asctl (audio server control) utility expands on avol with a
completely new command line interface (documented in the man page) that
supports retrieving and setting all exposed audio server settings, like
volume and sample rate. This is currently the only user-facing way of
changing the sample rate.

d049626f40 Userland+LibAudio: Make audio applications support dynamic sample rate
All audio applications (aplay, Piano, Sound Player) respect the ability
of the system to have theoretically any sample rate. Therefore, they
resample their own audio into the system sample rate.

LibAudio previously had its loaders resample their own audio, even
though they expose their sample rate. This is now changed. The loaders
output audio data in their file's sample rate, which the user has to
query and resample appropriately. Resampling code from Buffer, WavLoader
and FlacLoader is removed.

Note that these applications only check the sample rate at startup,
which is reasonable (the user has to restart applications when changing
the sample rate). Fully dynamic adaptation could both lead to errors and
will require another IPC interface. This seems to be enough for now.

02e3633b7f AK: Move FormatParser definition from header to implementation file
This is primarily to be able to remove the GenericLexer include out of
Format.h as well. A subsequent commit will add AK::Result to
GenericLexer, which will cause naming conflicts with other structures
named Result. This can be avoided (for now) by preventing nearly every
file in the system from implicitly including GenericLexer.

Other changes in this commit are to add the GenericLexer include to
files where it is missing.

332b29c741 LibTest+Utilities: Print a start message before each test in run-tests
It can sometimes be difficult to tell from the debug.log and test stdout
which test was the last to run before the test runner hangs or exits the
QEMU instance unexpectedly.

Print out a start message before each test is executed, along with a
progress message indicating which test out of how many tests we're about
to run.

a9cbdcbcd0 Utilities: Make aplay respect loader errors
aplay would previously just retry a couple of times when the loader
encountered an error, even though there is a standard mechanism for
loaders to report errors. Now, aplay outputs these errors to the user
and exits.

6c9343e262 Userland: Also cache d_type in find(1)
Since readdir() actually gives us the file type, we don't have
to stat it again to know whether it's a directory! This means that
'find /' can process the majority of files without ever calling
stat() on them, simply by reading directories.

In addition, the TypeCommand (-t) can make use of this info too,
so, for instance, a 'find / -t d' does not need to stat anything
either.

This gives us a final huge speedup :^)

548a880310 Userland: Cache stat in find(1)

ad15d0c880 Userland: Ditch Core::DirIterator for readdir() in find(1)
While Core::DirIterator is nice C++ API, we want more low-level
control here. In particular, we want to open the directory using
openat(), to also not pay the cost of re-traversing the path
components we have already resolved previously.

This gives us another nice speedup :^)

Also, in the future commits this will allow us to make use of more
data from the returned struct dirent, to speed things up even further.

4c126ea908 Userland: Use fstatat() in find(1)
This speeds things up noticeably :^)

The idea here is that a directory fd is a way to hold onto
the results of path resolution that the kernel has already done
for us. This way we don't ask the kernel to resolve the same
parent directories over and over.

bf1adc2d5d Kernel+LibC: Use 64 bit values for ino_t
Since the InodeIndex encapsulates a 64 bit value, it is correct to
ensure that the Kernel is exposing the entire value and the LibC is
aware of it.

This commit requires an entire re-compile because it's essentially a
change in the Kernel ABI, together with a corresponding change in LibC.

0286160b62 Kernel: Add syscall performance event type
This allows tracing the syscalls made by a thread through the kernel's
performance event framework, which is similar in principle to strace.

Currently, this merely logs a stack backtrace to the current thread's
performance event buffer whenever a syscall is made, if profiling is
enabled. Future improvements could include tracing the arguments and
the return value, for example.
