Implement MmAllocateMappingAddress and MmFreeMappingAddress routines.
Based on mm-implement-mappingaddress.patch by Thomas Faber with some changes from me.
Required by Microsoft NTFS driver (from Windows Server 2003 SP2 only, the one from Windows XP SP3 does not need them) and by NDIS & TDI drivers (both from Windows XP SP3 and Windows Server 2003 SP2). Also they are called when using Dr. Web Security Space 8 filter drivers together with MS FltMgr & TDI.
Fortunately, this part (these two routines) are enough to get the drivers working in both cases, and others (partially incomplete) routines are not badly required, so they can be finished and committed later.
CORE-10147, CORE-14635, CORE-17409, CORE-19318
These headers come with the MS compiler. Some of them are standard, like emmintrin.h, others are MS specific like crtdefs.h
This separation will allow using MS CRT headers. Eventually it can allow compiling with the compilers' runtime headers.
- no functional change intended
- shrinks the rc files sizes and shrinks the binary size of taskmgr:
RosBEWin2.2.2 GCC8.4.0dbg taskmgr.exe from 696.320 -> 678.912 bytes ==> 17.408 bytes saved in the binary
- does also slightly beautify those lines when displaying them in the reshacker

Proposed changes
Timeout parameter of those two functions should be optional.
Instead link to cpprt. This fixes build with GCC 13, which generates symbols that conflict with __cxa_pure_virtual, if there is a pure virtual function in a vtable. Importing __cxa_pure_virtual from a library works for all versions of GCC.
Make these definitions compatible with the other ambient size_t and
(u)intptr_t types used in the rest of our code base.
This partly reverts the corresponding typedef changes from wine commit
d8ab5a14aa
"msvcrt: Use intptr_t or size_t instead of long where appropriate."
Refine the algorithm introduced in commit c560342f08 (r75667, r75676),
whereby the installation source path is based on the full image file path
of the installer program, and of the \SystemRoot symlink.
Also reverts commit 6f389a35db "Add a workaround for installing from USB drives"
CORE-17818
+ SAL2-annotate and add Doxygen comments.
----
In case the \SystemRoot full path prefixes the image file path,
use the resolved \SystemRoot as the installation source path.
Otherwise, use the image file path.
The \SystemRoot symlink target resolution needs full path reparsing,
because it can reference other symlinks. This is what happens, for
example when booting the installation from a removable hard-disk.
We can have:
\SystemRoot ---> \Device\Harddisk1\Partition1\ReactOS
and: \Device\Harddisk1\Partition1 ---> \Device\HarddiskVolume2
etc.
and we wish to resolve \SystemRoot to: \Device\HarddiskVolume2\ReactOS
instead of keeping the former version (using Harddisk1\Partition1).
We then verify whether it prefixes the image file path, which is
a fully reparsed path.
Based on the Doug Lyons' test in #7087, I found that my previous fix stopped working partially. Or rather, it would only work until the 32767 indexes were exhausted. It seems to me that the behavior of the bitfield has changed, because when I published the previous patch, it passed my tests.
- Bit array generates free ID cyclically, in the previous code after 32767 indexes expired the same index was returned, because of this the previous fix would stop working after expiration, so change the logic of calculating the next index.
- Change the index range to 256-32767 to match Windows, indexes 0-255 can theoretically be used as reserved for system purposes.
Addendum to fd327db20f. CORE-9141
According to tests, legacy fp state is not saved in kernel mode.
Also add an int 2c to the path that changes cs, as it should not be used and probably never will be.
