5c99d63970 Merged branch haiku/branches/developer/bonefish/vm into trunk. This
introduces the following relevant changes:
* VMCache:
  - Renamed vm_cache to VMCache, merged it with vm_store and made it a
    C++ class with virtual methods (replacing the store operations).
    Turned the different store implementations into subclasses.
  - Introduced MergeStore() callback, changed semantics of Commit().
  - Changed locking and referencing semantics. A reference can only be
    acquired/released with the cache locked. An unreferenced cache is
    deleted and a mergeable cache merged when it is unlocked. This
    removes the "busy" state of a cache and simplifies the page fault
    code.
* Added VMAnonymousCache, which will implement swap support (work by
  Zhao Shuai). It is not integrated and used yet, though.
* Enabled the mutex/recursive lock holder asserts.
* Fixed DoublyLinkedList::Swap().
* Generalized the low memory handler to a low resource handler. And made
  semaphores and reserved memory handled resources. Made
  vm_try_resource_memory() optionally wait (with timeout), and used that
  feature to reserve memory for areas.

c76695a275 * The C "struct list" and the C++ DoublyLinkedList implementations had mixed
next/prev link order - that messed up the DoublyLinkedListCLink adapter.
* Since it's more likely that someone messes with the C version, the C++ version
  now uses the same order than that one.
* This fixes a bug when TCP's BufferQueue tried to iterate over a list, messing
  up its integrity.

5102d49461 * Added the default constructor to the Iterator class.
* Added a Current() method to the same class that returns the current element again.

9781d591cb Include <util/kernel_cpp.h> in DoublyLinkedList.h only when compiling
for the kernel. Added missing includes in userland code that uses the
header.

0dd2e9c328 * Changed Insert() to not only compile but also work differently in that it
inserts the item before, and not after the given element (that's probably
  what you expected anyway).
* Added ReverseIterators.

c47f661799 * Added a template class to bridge over to the struct list C stuff.
* Added an Insert() variant that can insert an element behind another one.

c918a987a0 * Removed my old doubly linked list implementation, and stay with Ingo's.
* Adapt other sources where needed (the boot loader's RootFileSystem still
  used the old implementation).
* Implemented RootFileSystem::Rewind().

758b1d0e05 Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
  declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
  explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
  something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
  'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
  is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
  Otherwise the an inner class with that name is considered as friend.
  gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

50d68edcf4 It's fun to rename functions in templatized code. You only realize, that you missed some, when that specific part is instantiated.

2cfdb0ed38 * Added DoublyLinkedListMemberGetLink class which directly accesses the
link member in the element class. Usually more comfortable for structs.
* Added Add() method as synonym for Insert().
* Made fGetLink member static to save memory in objects using it.

297ffaeb84 Appended the new DoublyLinkedList implementation to DoublyLinkedList.h. The old implementation will go, when all the places where it is used have been adjusted.

3f7d503ff1 Fixed DoublyLinkedList::Iterator().
Switched back to a pointer to the list in the Iterator internally, so
that it can still be just copied without having to overload "=", etc.
This fixes the boot loader build, too (shame on me).

8174112d40 Almost straight copy of the list.h doubly linked list implementation to
a C++ one ready for kernel use, but very basic, too.
Has not been tested yet, expect some bug fixes soon.
