8e074f8665 LibC+LibPthread: Implement pthread_rwlock_* 
This implementation is pretty damn dumb, and probably has more bugs than
features.
But for the time being, it seems to work. however, we should definitely
replace it with a good implementation sometime very soon :^)

9efd80f100 LibJS: Use fabs() instead of abs() in JS::Value 
abs() takes an int, so this would only work correctly for numbers
smaller than INT_MAX.

1c6fd749dc LibCrypto: memcmp() all bytes in UnsignedBigInteger::operator== 
`length` is only the (trimmed) size of the word vector, so we have to
multiply it with the size of each element to ensure all bytes are
compared.

Fixes #5335.

a6fdc17f3f LibGUI: add 'always_wrap_item_labels' property to IconView. 
In some circumstances (like template selection dialogs,) displaying as much
item label as possible, on all items, may be desired.

The default setting is 'false', which matches the default behaviour from before;
only wrapping on hover or selection.

e8d3856736 LibJS: Randomize GC heap block locations 
Allocate GC heap blocks with mmap(MAP_RANDOMIZED) for ASLR.

This may very well be too aggressive in terms of fragmentation, and we
can figure out ways to scale that back once it becomes a big problem.

For now, this makes the GC heap a lot less predictable for an attacker.

This wrapper abstracts the watch_file setup and file handling, and
allows using the watch_file events as part of the event loop via the
Core::Notifier class.

Also renames the existing DirectoryWatcher class to BlockingFileWatcher,
and adds support for the Modified mode in this class.
