The glibc libm code was showing its age, and has recently been
the subject of a number of tickets about its inaccuracy.
Additionally, some developers have complained about
how convoluted the headers are, and thus how hard it is
to add support for new architectures (and how flaky
the support for the existing architectures is.)
So, with this commit, nearly the entire glibc libm has been
gutted and replaced with the one from musl 1.1.24.
The complex functions from glibc are retained (as they
are more mature than musl's), as are some glibc-internal
libm functions.
This also has the advantage that these functions are
actually using our <math.h>, whereas GCC used its own,
which was rather dangerous for obvious reasons.
Additionally, the new math functions are always compiled
with GCC 8 (even on x86_gcc2), as it seems GCC 2 does
not quite understand some of the union-aliasing they
use (a lot of which was added in C99, I suppose.)
FFmpeg on x86_gcc2 is already compiled with GCC 8
and that has so far worked out well, so there should
not be any problems caused by this.
I did verify that ARM and PPC at least still compile,
though other architectures may require a bit more work
(they are not bootstrapped so I could not do much.)
Should fix#14933 among other issues.

Get enough of the mmu working to be able to allocate memory.
Unlike on PowerPC, we get both address and size as 64bit values. So
adjust of_region to allow this.
Also unlike the PPC port, we do not drive the hardware directly, instead we
rely on the openboot primitives to manage the translation table. This
allows staying independant of the hardware, which is a good idea at
least for the bootloader (we can do actual hardware things in the
kernel)

There is no /cpus in the device tree on my machine, the CPUs are instead
directly under the root. So search for them there.
There is also no timebase property, and according to the docs, the
RDTICK instruction just gets CPU clock ticks, so set them to the same
value for now.
The two CPUs in my reference machine are succesfully found now, yay!

get_test_app_ref() computes a path relative to
BTestShell::GlobalTestDir() that is supposed to contain test apps that
will be launched with launch_test_app(). The path is incorrect so
several tests fail.
The test apps are actually just in BTestShell::GlobalTestDir(). Fixing
this resolves 6 of the 12 failing tests in the BRoster tests.

Fixes#15548.
This change disables immediate drawing of background on expose and makes drawing background a part of the update session. In previous version expose/update separation is incorrect in some cases. For example when view with B_FULL_UPDATE_ON_RESIZE is resized, it will be updated with expose cause, that will trigger flickering. Correct handling should be update on old visible area and expose on area that became visible. If immidiate exposed area erasing is preferred, it need more work to fix. Anyway delayed redrawing cause problems only on slow machine or on slow responding applications, but current master approach cause flickering even on fast machines and on any application that use non-transparent view color.
Multiple expose/update requests also seems not work properly.

glibc does the same. Technically, some of these builtins did
not exist / did not work before GCC 4.4, but the source tree
cannot be compiled with a version that old anyway.
x86_64 and _x86 need to keep the old functions for now, of
course; but all other architectures can probably feel free
to drop the s_isnan, etc. functions from their glibc.
This will make upcoming patches easier...

- Remove some old #if 0 code that touched these registers but has been

LVDS panels must really be driven at their native resolution, otherwise
they will simply not work. This means we should basically never touch
the video timings on that side. We need to only set the source size in
the pipe configuration, and let the panel fitter figure out the scaling.
On my G45 laptop, this allows me to use non-native resolutions on the
laptop display. This also means when booting with a VGA display
connected, I do get a valid display on the internal panel (using the VGA
resolution). VGA still gets "out of range", so we're still not setting
up something there.
If I switch to VGA display in the BIOS, I get a working picture there
and garbage on the internal display, which is progress (before I would
get a black screen on the internal display)

The "generic" files are actually not generic at all. They were
imported for the PowerPC port and assume a matching format for float.
However, x86 uses a different format as the values are stored with 80
bit precision in the FPU. Therefore the generic implementation is
not appropriate whenever it does bit manipulations.
The glibc implementation uses the same sourcecode as the x86 version
for atan2, and there is no reason for us not to do the same.
Should fix#14933

This patch fixes a bug in the BMemoryIO unit tests that made them
fail and adds an additional test case for read-only buffers.
The failing test case invokes BMemoryIO::WriteAt() with the position
parameter set to -10, which is invalid and should result in a return
value of B_BAD_VALUE. And it does, but the test fails because it was
testing for the return value 5, as in 5 bytes copied.
An additional test case is added for read-only BMemoryIO objects. If
the BMemoryIO(const void*, size_t) constructor is used then it will be
marked as read-only, so writes should fail with B_NOT_ALLOWED.
