Make sure to check for invalid NULL handles before passing them to GDIOBJ_bLockMultipleObjects, which skips NULL handles. This is a design limitation, since otherwise we either need to pass a bitfield of valid handles, or duplicate code in certain functions, where different combinations of dest, source and mask dc are allowed.

When a user mode debugger has single stepping enabled and steps over a sysenter instruction, you are obviously not supposed to enter the kernel debugger on the syscall entry handler. But exactly this happened on reactos. This was because the sysenter instruction doesn't disable single stepping, so we need to handle this special case manually in the single stepping handler (which we didn't). We now check if the single step comes from KiFastCallEntry and when it does, disable single stepping in the current (nested) trap frame and return back to a secondary fast call entry. The 2nd entrypoint will make sure to re-enable the single step flag in EFLAGS before returning to usermode.
To make this actually work, the asm entry stub itself needs to handle saving of eflags, so some trap frame modification from KiFastCallEntryHandler was moved into the asm stub. Since the amount of asm instructions is rather small (10 instructions, pretty straight forward) I moved everything from KiSystemServiceHandler to the asm stub and killed KiFastCallEntryHandler entirely, calling KiSystemServiceHandler instead.
Now stepping over a sysenter instruction works with OllyDbg without breaking into the kernel debugger. CORE-8057 #resolve

- Fix a failed partition type assignment, when unpartitioned disk space is converted to an extended partition.
- Rename the extended partition list to logical partition list.
- Add a pointer to an extended partition to the disk entries. And keep it up-to-date when the primary partition list is built or modified.
- Add the 'Unpartitioned space' partiton entry to the logical partition list when an extended partition has been created.
- Remove all logical partition entries when the coresponding extended partition will be deleted.

Also, for reference: r23894 contained working implemnentations in fpu.c. In r23895 ion "moved" it to cpu.c, killing the MSVC implementation in the process. In 23972, ion added new MSVC code for it, but this new version had the bug. It has remained undiscovered until very recently.

Use a separate palette for text mode. Previously the text mode palette was equal to the
first 16 entries of the graphical palette, which is wrong since the AC registers can be
used to select arbitrary colors from the DAC.
