2323b6fb74 LibWeb: Use the correct DOM node when moving text cursor with mouse 
We should use the DOM node returned by the TextCursor hit test,
and not the one we got from the earlier Exact hit test.

non-rectangular window frames.

cf0d4994c2 LibC+LibPthread: Permit partial pthread_atfork 
POSIX explicitly allows providing nullptr's, and our __pthread_*() implementation
stores and calls the provided functions as-is, without checking for nullptr.

015c5e61a8 LibGUI: Fix bogus TextEditor selection when cursor dragged outside view 
If the cursor Y position is < 0 in content coordinate space, we should
always map that to the first line of the file.

This fixes unexpected cursor behavior when dragging the selection above
the top of the document.

5729e76c7d Meta: Make it possible to (somewhat) build the system inside Serenity 
This removes some hard references to the toolchain, some unnecessary
uses of an external install command, and disables a -Werror flag (for
the time being) - only if run inside serenity.

With this, we can build and link the kernel :^)

bb777459a0 LibC+LibPthread: Implement pthread_atfork() 
This required a bit of rearchitecture, as pthread_atfork() required a
mutex, and duplicating a mutex impl for it was silly.
As such, this patch moves some standalone bits of pthread into LibC and
uses those to implement atfork().
It should be noted that for programs that don't use atfork(), this
mechanism only costs two atomic loads (as opposed to the normal mutex
lock+unlock) :^)

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.

the same family and weight or a pointer to a single TTF font
for all sizes of this Typeface.

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.
