mapped fully read-only (for both kernel and userland). Previously a
kernel read access to a yet unmapped r/w accessible userland address
would cause the page from the lower cache to be mapped with write
permission for userland (on x86 also for the kernel) thus e.g.
allowing a fork()ed child process to write to the parent process'
memory.
Fixes bugs #113 and #928.

and #928. Under certain conditions a fork()ed child process can
write to the parent process' memory.
A fix follows...

{set,clear}_debugger_{break,watch}point(), allowing to set/clear break
and watchpoints for the calling team. When a break/watchpoint is hit,
the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.
We clear the arch specific team and thread debug infos now, when a new
debugger is installed, thus clearing break- and watchpoints.

updated with Release B3 (I didn't test yet) :
-Firmware to support new revision 5 Indigo io and Indigo dj hardware
-Firmware to support new revision 4 Mia MIDI hardware
-New FPGA & DSP code to correct problems with S/PDIF at 96 kHz on Gina3G (note new,
longer timeout required in C3gDco.cpp)
-Changes to support x64 Windows
-Fix for 96 kHz on Mac OS X for Echo 3G
-New QuerySampleRateRange method for all devices
-Simplified channel mask classes
-New ECHO_ASSERT macro to simplfy enabling and disabling asserts
-Removed m_wBytesPerSample from CEchoGals; it wasn't being used and caused housekeeping problems for Adobe Audition recording in mono mode
-Now using READ_REGISTER_ULONG and WRITE_REGISTER_ULONG macros to read and write DSP registers; these
are automatically defined if the platform environment doesn't define them.

valid stderr. Thus one of the FDs for the pipes created for the initial
handshake with the fork()ed child process exec()ing the shell would have
number 2 and would be closed when the child process set up the
stdin/out/err environment for the shell, leading to the child and the
parent being killed by a SIGPIPE when they tried to access the pipes.
This change replaces the pipes mechanism by one using send/receive_data(),
which is probably even faster. I also reduced the handshake_t::msg field
to 128 bytes and replaced the sprintf()s writing to it by snprintf()s.
Fixes bug #627. Although they looked related, bugs #113 and #928 still
persist.

list in the other direction.
* Since WorkspacesLayer now cuts out the current window from the clipping region,
the window order was upside down; it now uses the new Workspace::GetPreviousWindow().
This fixes bug #1105.
* WorkspacesLayer::MouseDown() now also uses GetPreviousWindow() which prevents it
from needing to scan the whole window list for the top window at every click.

* NewBlock()/FreeBlock() are now symmetrical in that the former no longer inserts
the block into the hash table.
* delete_transaction() also no longer removes the transaction from the hash table.
* cache_transaction_sync() now uses the new hash_remove_current() function.
* minor other cleanup (like line breaks).

start address wasn't aligned and numBytes was a multiple of the page
size, the last page was ignored. A subsequent get_memory_map() would
return NULL as physical address for that page, if it hadn't been mapped
before (that function looks generally suspicious, IMHO). E.g. reads from a
device into an unaligned buffer that hadn't been touched before would
hit that problem. Fixes bug #1075. Might also fix other reported
problems (like #1056), since this bug could have cause all kinds of weird
behavior and crashes.

that points to both, the page and the area the page is in. This will allow a page
scanner to steal unused pages when necessary.
* The locking is currently done with a spinlock which we might want to have another
look at one day.
* dump_page() and dump_area_struct() now dump the page mappings as well.
