c5e9dd9b68 Fix btrfs_shell build
The hacks to still use actual system headers for zlib didn't quite work.

- Define Z_SOLO, which makes zlib build without any system include
- Remove use of std::max and #include <algorithm> from AVLTree
- Do not include DebugSupport.h because it uses system headers
- Do not include uuid.h and define just what we need

Now it's possible to compile the btrfs_shell on Linux.

7b4d924f98 cpu: Extract shared x86 code from efi & bios_ia32
This issue was initially detected by PVS Studio (issue number V547) and fixed
as part of Google Code-in 2019.

The initial problem was the calculate_cpu_conversion_factor function
which had been copied in the BIOS and EFI versions of the boot code.
Further investigation led to more duplicated or very similar functions
being identified.

Introduce an arch_cpu.h for the x86 boot platform to group these things
in a single place, and adjust the BIOS and EFI code to call into that.
Note that the BIOS and EFI code is still a little platform specific,
ideally there should be a boot_arch_cpu_init() function for each
architecture as already done for openfirmware and u-boot.

Also remove some irrelevant comments from copypasted files for other
architectures, as that was filling my git grep with useless noise.

56f9c76088 sparc: boot mmu support
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)

to provide C89/C99/C++98/C++11 compatibility, in which case we still
need them around.

cf344027f8 kernel: Add padding in mutex fields for equivalent KDEBUG/non-KDEBUG sizing.
Non-KDEBUG kernels and kernel add-ons use atomic operations to acquire
and release the locks inline, so non-KDEBUG kernels/addons are only
compatible with other non-KDEBUG kernels/addons.

Following this change, though, KDEBUG kernels/addons should be able
to run under non-KDEBUG kernels/addons, too, since they always call
into the actual kernel functions and do not inline anything of
consequence.

This adds one (private) VFS function, and checks in all usages of
the vnode->cache as a VMVnodeCache that it really is one. (Generic
usages, for the moment just the ReleaseRef() calls in vnode
destruction, are intentionally not touched.)

This will be used by ramfs to set the cache from its own,
so that map_file() calls on a ramfs can work.

The patched errata are only the AMD ones FreeBSD patches

be patched in the CPU at all.)

This also seems to be roughly the point in the boot that
FreeBSD patches these, too, despite how "critical" some
of them seem.

d5cd4a9d51 openfirmware: adjust for 64bit
Sparcv9 runs Openboot in 64 bit mode, which means the cell size is
64bit. Use intptr_t where appropriate to make the open firmware calls
work.

Beware, some values are still 32bit, this matters for example for
of_getprop, if you get 32bits into a 64bit variables it will be in the
MSB of it (big endian only weakness...) and confuse things. See for
example in console.cpp, where the input and output handles are retrieved
as 32bit values. It seems wise to check the expected size when using
of_getprop in these cases, instead of just checking for errors.

37eda488be kernel/condition_variable: Granularize locking.
Before this commit, *all* ConditionVariable operations (yes, all;
even Wait, Notify, etc.) went through a single spinlock, that also
protected the sConditionVariableHash. This obviously does not scale
so well with core count, to say the least!

With this commit, we add spinlocks to each Variable and Entry.
This makes locking somewhat more complicated (and nuanced; see
inline comment), but the trade-off seems completely worth it:

(compile HaikuDepot in VMware, 2 cores)
before
real 1m20.219s
user 1m5.619s
sys  0m40.724s

after
real 1m12.667s
user 0m57.684s
sys  0m37.251s

The more cores there are, the more of an optimization this will
likely prove to be. But 10%-across-the-board is not bad to say
the least.

39665db167 kernel/vm: Inline the VMArea::name string.
B_OS_NAME_LENGTH is 32, char* is 8 (on x64), and this structure
has quite a lot of pointers in it so it is not like we really
needed to save those 24 bytes. Hitting malloc() in here is not
so great, especially because we usually have B_DONT_LOCK_KERNEL_SPACE
turned on, so just inline and avoid it.

42e3c6f978 KPath: Use an object_cache for the path buffers in the normal case.
This was (following the packagefs changes) the number-one (by call
count) consumer of malloc() during the boot -- 52866 calls, and 100%
of them either 1024 or 1025 bytes!

Virtually all of these are ephemeral (indeed, the object_cache
stats after a boot with this patch shows there is only a single slab
of 64 buffers allocated, and most of them unused), so this is
probably a significant performance boost.
