54711c1b89 free() now fills the freed memory with 0xdeadbeef if PARANOID_KFREE is defined
(except for the first 4 bytes, because that's the pointer to the next buffer
in the free list).

d9e72f220a Reenabled the broken assert in free() and applied Travis' NewOS patch 1764
(which fixes that assert).

41691b996a Replaced kmalloc(), kfree(), and kstrdup() with the POSIX equivalents.
Implemented realloc().
Adapted all other sources, some minor cleanups in some files as well.

36cfa7d4f8 The USE_WALL setting currently doesn't work, because
vm_translation_map_create() checks if the kmalloc()'d page is aligned - maybe
we should just disable the USE_WALL setting if size is PAGE_SIZE for now...

3904aa6bf1 Shouldn't do anything so late; just fixed another bug in the wall code.
Commit early, commit often, they say...

a3da50e5ed Fixed a bug in the wall code that actually produced the bug I mentioned
in the last commit... :/

ebe92efe60 Added a front and back wall to each kmalloc() allocation, if USE_WALL is
set to 1 (which it currently is).
I've only used it with bochs yet, and it lets it crash reliably in some
VFS code.

4bb2d8915b Implemented geist's recent change to mutexes - they are now no longer
benaphores; benaphores aren't that beneficial in kernel land, the benaphores
are a way to reduce the number of kernel calls.
They can now only be released by the same thread who originally acquired it.

Included other changes geist (change 1499) did to a) fix some bugs, and
b) reflect the changes made to the mutexes.
Cleaned the files a bit up, all the commented dprintf()s in elf.c are now
deactivated through a macro.
