08cd75ac4b Kernel: Rename FileDescriptor to FileDescription.
After reading a bunch of POSIX specs, I've learned that a file descriptor
is the number that refers to a file description, not the description itself.
So this patch renames FileDescriptor to FileDescription, and Process now has
FileDescription* file_description(int fd).

bba2c062fe FileSystem: Make Inode::lookup() take a StringView.
This avoids a lot of String allocation during path resolution.

2e14e5891c FileSystem: Remove now-unused Inode::parent() and Inode::reverse_lookup().
These were only used to implement the old path resolution algorithm.

9ac95d1867 FileSystem: Pass mode_t to Inode::add_child().
This way the Ext2FS code can update its directory entry "file type" fields
correctly based on the file mode. This fixes some e2fsck whining.

55821c91f8 Kernel: Rename Process::cwd_custody() to Process::current_directory().
...and executable_custody() to just executable().

393851418b FileSystem: Port most of the code over to using custodies.
The current working directory is now stored as a custody. Likewise for a
process executable file. This unbreaks /proc/PID/fd which has not been
working since we made the filesystem bigger.

This still needs a bunch of work, for instance when renaming or removing
a file somewhere, we have to update the relevant custody links.

58240fdb33 Do a pass of compiler warning fixes.
This is really making me question not using 64-bit integers more.

d384c7815f Kernel: Make it possible to have kmalloc() dump call stacks.
This can be enabled at any time using a sysctl:

    sysctl kmalloc_stacks=1

The stacks will go to the debugger output only.

e9c0f4567d Kernel+ProcessManager: Expose the number of kmalloc/kfree calls.
This will be very helpful in tracking down unwanted kmalloc traffic. :^)

c0fe48635b Kernel: Add /proc/uptime file (number of seconds since boot.)
Also added a simple /bin/uptime to pretty-print this information. :^)
