bece4ef7ab Implemented driver unloading. When a driver is rescaned and doesn't publish
any devices anymore it gets unloaded. Also made sure the function pointers
are properly initialized and disabled debug output.

4fc4f2c8ae * Added a transaction listener mechanism to be notified when a
transaction ends or has been aborted.
* BFS now listens for transactions when it created an inode to see if 
  the transaction will be aborted without freeing the inode (in which 
  case it will panic for now).
* Started implementing tracing support, but it's not working yet.
* Minor cleanup.

5276dad057 * Fixed a bug in make_space() that would endlessly skip entries, even
though there was nothing to do (if 'diff' was larger than 'needed').
* Improved KDL command output.
* Added debug output to the allocation functions.
* Minor cleanup.

8e43ece8b8 Some more work on the tracing API:
* Added function to allocate space in the buffer.
* Dump() now fills a buffer instead of printing its data directly.
* This allows the new "#pattern" argument of the "traced" command to 
  work. When you're using that, the index of the trace entry is printed
  out, too, so that you can then get a full dump around the hits.
* Added an AddDump() method to the AbstractTraceEntry class so that 
  there is no need to call the inherited function anymore.
* Minor cleanup.

416458e9c4 * Added nothrow to the new operator because otherwise the C++ compiler
will not accept if the allocator returns NULL and crashes instead
  (ie. not compiling in tracing would have crashed if some module tried
  to use it).
* Added total entries count to the KDL command output.
* Fixed computing the start index of the KDL command.

a52c1759ac Fixed two bugs in the vnode disconnecting code found by bonefish+mmlr:
* vfs_disconnect_vnode() did not put away its vnode reference.
* disconnect_mount_or_vnode_fds() did always throw the current working
  directory of all apps on the same mount away, even if only a specific
  vnode should have been disconnected.

34b3b26b3b Merged branch haiku/branches/developer/bonefish/optimization revision
23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
  it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
  the assembly handler which now uses a jump table to call C functions
  handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
  interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
  rare events (signals, user debug enabling/disabling) on the
  common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
  retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
  the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
  common functions (currently memcpy() only). They are used in the
  kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
  member offsets in assembly code.

Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
  (caused by refactoring and introduction of "call" debugger command).

3e5b9076f9 * Fixed (or rather, worked around) a deadlock in the VM: when a file was
resized but still had dirty pages to be written back, 
  vm_cache_resize() (which is called with the inode lock being held)
  deadlocked with the page writer.
* Now, I reintroduced busy_writing: it'll be set by everything that
  writes back pages (vm_page_write_modified(), and the page writer),
  and will be checked for in vm_cache_resize() - other functions are not
  affected for now, AFAICT.
* vm_cache_resize() will clear that flag, and the writer will check it
  again after it wrote back the page (which will fail when it's outside
  the file bounds), and if it's cleared, it will get rid of the page
  (if the file has been resized again in the mean time, writing it will
  succeed then, and we'll keep the page around).

bcb71f00e8 * My last change to vm_page.cpp made an existing bug much more likely to
appear: when freeing a modified page, it wouldn't have a cache
  anymore, but set_page_state_nolock() depended on it.
* To work around this, I added a vm_page_free() function, which the
  caches that free modified pages have to call (but others may, too).
  It will correctly maintain the sModifiedTemporaryPages counter in case
  the cache has already been removed.

f4748003ed * Added a KDL function "call" that can show the arguments together with
a function in the stack trace (only works reliably when a stack frame
  is exists, and you'll have to know the number of arguments).
* Refactored the functions a bit and extracted setup_for_thread() out
  of stack_trace() to be used by show_call() as well.

4accd841c7 * Fixed a big bug in common_file_io_vec_pages(): vecOffset was not correctly
set when the first chunk of the file could be read in directly, causing it
  to read data to a wrong place in the buffer.
* Reading in the first chunk directly would have also only worked if vecIndex
  and vecOffset was 0 when calling the function.
* Applied the fs_shell changes in file_map to the kernel version as well (the
  constructor already worked correctly, though).

b938008fe1 * Update the PAUSE macro from "rep; nop;" to "pause;" which is the same bytecode wise but more readable
* Insert the pause op in all spin wait loops (as macro for platform independent sources or as inline assembly on x86 only files)
* Fix some warnings with tracing on and extended some output
* Minor cleanups here and there

The pause instruction is implemented since P4 systems but is fully backwards compatible (it's a no-op prior to P4). According to Intel specs it reduces performance penalties as memory order violations can be avoided. Also power consumption is reduced. Most of all this will be beneficial to hyper-threading systems as it frees resources to the other logical processor when one logical processor executes a fast spinning loop.

dfa4dfe033 Something else that has been laying around for some time. Implemented hash_grow() that can grow a hash table to a new table size. Automatic growing is commented out in hash_insert() since there needs to be a way to disallow growing in certain cases (i.e. where no allocations can be made). This is detailed in the ToDo at the top of the file.

  impossible, it was NULL once.
