According to the OpenGL 2.x spec, some calls will set the current
global error to `GL_INVALID_OPERATION` if they are used during
a `glBegin`/`glEnd` block.
This implements `glGetError` and correctly sets the state machine's
error macro (similar to LibC `errno`) when an invalid operation is
performed. This is reset on completion of a successful operation.
This currently (obviously) doesn't support any actual 3D hardware,
hence all calls are done via software rendering.
Note that any modern constructs such as shaders are unsupported,
as this driver only implements Fixed Function Pipeline functionality.
The library is split into a base GLContext interface and a software
based renderer implementation of said interface. The global glXXX
functions serve as an OpenGL compatible c-style interface to the
currently bound context instance.

When using open() with the O_CREAT flag we must specify the mode
argument. Otherwise we'll incorrectly set the new file's mode
to whatever is left on the stack:
courage:~ $ dd if=/dev/zero of=test count=1
1+0 blocks in
1+0 blocks out
512 bytes copied.
courage:~ $ ls -l test
--w-r-x--- 1 anon users 512 2021-05-08 01:29:52 test
courage:~ $
This also specifies the mode argument when opening files for
reading. This however is harmless because in those cases the argument
is ignored.

Since we keep a stack of command combos, let's call entries on the
stack "Combo" instead of "UndoCommandsContainer".
And since it has a vector of commands, let's call it "commands"
instead of "m_undo_vector".
A Frame now knows about its nesting-level.
The FrameLoader checks whether the recursion level of the current
frame allows it to be displayed and if not doesn't even load the
requested resource.
The nesting-check is done on a per-URL-basis, so there can be many many
nested Frames as long as they have different URLs.
If there are however Frames with the same URL nested inside each other
we only allow this to happen 3 times.
This mitigates infinetely recursing <iframe>s in an HTML-document
crashing the browser with an OOM.

I noticed while testing `find` that the output of `find` contains extra
forward slashes if the root path has a trailing slash. This patch fixes
that issue by passing the root path through LexicalPath before
proceeding.
