We now keep track of a lower bound as to when the list should scale
itself back down. When increasing the list size, we double the current,
with the lower bound set to 1/4 of the current size, not allowing it to
go any smaller than the block size. These combined allow us to do very
cheap tests to see if an operation requires a resize at all, and minimize
how often the list actually needs to be resized, since the difference in upper
and lower bounds prevents bouncing back and forth between a size in the case
of adding/removing an item while close to a boundary. All in all this should
make BList noticably more scalable when doing large numbers of add/remove
operations.

- Tailor a bit the main module
- Fix definitions in the main header

* Added B_BITMAPS_SUPPORT_OVERLAY flag to indicate overlay support for the
color space.
* Rewrote GraphicsDefs.h - the previous one was obvious a copy of the Be header,
including typos and strange white space. I was a bit lazy with respect to
the color space details, and mostly trusted the information provided by the
Be header else.

B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a
structure (thus breaking BeOS binary compatibility), containing a
counter which is incremented whenever a thread has to wait for the
spinlock.
* Added macros for spinlock initialization and access and changed
code using spinlocks accordingly. This breaks compilation for BeOS --
the macros should be defined in the respective compatibility wrappers.
* Added generic syscall to get the spinlock counters for the thread and
the team spinlocks.

* Renamed scsi_dsk to scsi_disk.
* Joined all scsi_disk sources together to a single scsi_disk.cpp file.
* Cleanup.

the message count doesn't really make much sense anyway (as opposed to
limiting the maximum size of waiting messages), we might still want to
enlarge this even more.
* This should further help with #2212.
* Minor cleanup.

* Moved devfs from fs/ to device_manager/, and separated the legacy driver
support from it.
* Removed fast_log module.
* There are a couple of (temporary) regressions, though:
- legacy SATA and ISA IDE support is disabled, the drivers haven't been
ported yet.
- The not yet used ATA bus manager hasn't been ported yet, either.
- AHCI changes have not been tested.
- the listdev command has been removed from the build (as it currently
doesn't work anymore).
- device manager generated IDs currently are not freed anymore when a device
node is removed.
- generic drivers can't yet use the new driver architecture.
- simple busses that do not support device types won't work yet.
- legacy driver publishing/unpublishing (ie. what USB needs) has not been
tested, and may be broken.

Our font has some extra styles and these could be picked up as the
"regular" face by accident, as witnessed by Firefox. Tracked down by
Michael Lotz. Firefox uses the correct font now for it's interface.

* Added BDiskDeviceRoster::GetDiskSystem() method, that can get a disk system
by short/pretty/module name - since they should all be unique, I put them
in a single namespace, please complain if you don't like that :-)
* Cleaned up DiskSystem.h and DiskDeviceRoster.h according to the updated
header guidelines.
* Renamed ntfs pretty name from "ntfs File System" to "Windows NT File System".

compile time checks. Incidently those are not totally uncommon in
portable code.

this (seems to be what R5 BStatusBar does):
* combine the "trailing text" with the "trailing label" and truncate the
resulting string on the left side according to the width of the entire
control
* combine the "label" with the "text" and truncate that on the right side
according to the space left by the right hand text.
-> No more overlaps (theoretically, in practise there are still overlaps
because our BFont::TruncateString() does not respect the width in some
situations.)
* Changed _SetTextData() accordingly, it is not used anymore for the
label and trailing label, and could therefor be simplified a little.
* fixed _BarFrame() to not return fractional coords, which could sometimes
leave a dirty line of pixels.

* Also removed the header files that belong to those files.
* Only kept the userland_ipc.h header for now, to remember us about the
former userland server driver (that I also removed - it can always be
resurrected from SVN if needed).

(can't do it for GCC 2.95.3, since that would break binary compatibility
AFAIKT)

and some conflicts with BControls.
