d6e122fd3a Kernel: Allow contiguous allocations in physical memory
For that, we have a new type of VMObject, called
ContiguousVMObject, that is responsible for allocating contiguous
physical pages.

b066586355 Kernel: Fix race in waitid
This is similar to 28e1da344d
and 4dd4dd2f3c.

The crux is that wait verifies that the outvalue (siginfo* infop)
is writable *before* waiting, and writes to it *after* waiting.
In the meantime, a concurrent thread can make the output region
unwritable, e.g. by deallocating it.

d8cd4e4902 Kernel: Fix race in select
This is similar to 28e1da344d
and 4dd4dd2f3c.

The crux is that select verifies that the filedescriptor sets
are writable *before* blocking, and writes to them *after* blocking.
In the meantime, a concurrent thread can make the output buffer
unwritable, e.g. by deallocating it.

36ba0a35ee Travis: Cache toolchain
This should give a significant boost to Travis speeds, because most of the
compile time is spent building the toolchain over and over again.
However, the toolchain (or libc or libm) changes only rarely,
so most rebuilds can skip this step.

The hashing has been put into a separate file to keep it
as decoupled as possible from BuiltIt.sh.

0edae63cc0 Kernel: Fix inconsistent inclusion style
This also makes it easier to automatically parse the dependency tree.
Thankfully, this is the only place where a change was necessary.

32f15f3c45 AK: Remove unused InlineLRUCache template

900f51ccd0 AK: Move memory stuff (fast memcpy, etc) to a separate header
Move the "fast memcpy" stuff out of StdLibExtras.h and into Memory.h.
This will break a ton of things that were relying on StdLibExtras.h
to include a bunch of other headers. Fix will follow immediately after.

This makes it possible to include StdLibExtras.h from Types.h, which is
the main point of this exercise.

35d88f536c AK: Use __builtin_memset() and such to reduce header dependencies
We can use __builtin_memset() without including <string.h>.
This is pretty neat, as it will allow us to reduce the header deps
of AK templates a bit, if applied consistently.

Note that this is an enabling change for an upcoming #include removal.

b1058b33fb AK: Add global FlatPtr typedef. It's u32 or u64, based on sizeof(void*)
Use this instead of uintptr_t throughout the codebase. This makes it
possible to pass a FlatPtr to something that has u32 and u64 overloads.

f5476be702 LibJS: Start building a JavaScript engine for SerenityOS :^)
I always tell people to start building things by working on the thing
that seems the most interesting right now. The most interesting thing
here was an AST + simple interpreter, so that's where we start!

There is no lexer or parser yet, we build an AST directly and then
execute it in the interpreter, producing a return value.

This seems like the start of something interesting. :^)

f2f16e1c24 IPv4: Keep IPv4 socket locked during receive operations
We unlock/relock around blocking, but outside of that we now keep the
socket locked.

This fixes an intermittent ASSERT(m_can_read) failure.
