Kernel: Fix setting ext2 symbolic link target
...
If a link was >= 60 bytes but got shrinked to 60 bytes, reading it would
rebort garbage and unlinking it would leak blocks

Kernel: Fix deadlock in ext2 filesystem
...
If multiple threads were waiting for more block buffers without anyone
releasing them, they ended up in a deadlock.
Now we store 6 blocks for 8 threads. If a thread already has a block
buffer, it will not have to wait for a new one. Only if there are more
than 8 threads using blocks, will it block until there are free slots
for a thread available.

Kernel: Decrease the number of syncs done by ext2 inodes
...
Each allocated inode used to call sync(). Each sync reads and writes
a block from the filesystem. Doing a 1 MiB write ended up syncing around
257 times

Also replace unnecessary spinlocks from unix socket with mutexes

Kernel: Don't crash if Ext2 filesystem doing too many fileops

I had a hardlimit of 10 block buffers and if they ran out, the kernel
would crash. this patchs increases the number of buffers to 16 and
removes the crash condition when they run out :D

Kernel: Rewrite TmpFS block and inode allocation
...
This makes creating files and appending to then A LOT faster. Some code

second on the new one!
This code is really sketcy, I hope I'll never have to touch it again :)

All block functions now take an optional mutex parameter that is
atomically unlocked instead of having the user unlock it before hand.
This prevents a ton of race conditions everywhere in the code!

Kernel/LibC: Implement basic epoll
...
This implementation is on top of inodes instead of fds as linux does it.
If I start finding ports/software that relies on epoll allowing
duplicate inodes, I will do what linux does.
I'm probably missing multiple epoll_notify's which may cause hangs but
the system seems to work fine :dd:
