I'm very keen on being able to use the jdk.jartool module (which is only
available in JDK11 onwards) as it allows us to avoid shelling out to
jarsigner entirely.
11 is the current LTS release and is already widespread in Linux
distributions, so I think it's reasonable to require it.
This commit removes the jsobject module. We might need to re-add it in
the future (if jdk.jsobject is removed from the JDK). However, it was
only necessary in 8 because modern versions of 8 tended to be
distributed without plugin.jar. JDK11 is distributed with the
jdk.jsobject module.

The split is no longer required - we haven't run javah automatically
since splitting the natives out into a separate repository.

This is a special case, so I've just hard-coded the GlEnum name and
value. Luckily its value is only used in the client in an OpenGL
context.

It's actually hard to determine whether to use a vendor suffix or not.
For example, the client sometimes uses a bunch of *ARB functions with
_ARB constants. However, it uses the non-_ARB constant with glGetFloat.
It's very hard to fix this inconsistency while still using vendor
suffixes. It seems much easier to just use the constants without the
suffixes all the time.

Removes GOTO instructions that point to the next instruction, typically
left over from stripping exceptions inserted by the obfuscator.
Although modern decompilers can handle such GOTOs fine, removing them
makes for a nicer IR representation.

It's possible that future versions of ASM will introduce additional
types of virtual node. Only counting real instructions should make this
more reliable.

While it isn't useful for retaining the name of the constructor itself,
as they don't really have names, it will be useful for tracking argument
names and positions.

The transformer does _not_ check for use via reflection. The only cases
in the 550 and OSRS clients where methods are accessed via reflection
are either 1) JRE classes, 2) when the method name is sent from the
server.
PSVM and methods declared in TypedRemapper.EXCLUDED_METHODS are never
removed.

Fernflower fails to decompile any exception handler with an end_pc
(`to` in Fernflower nomenclature) equal to the length of the code array,
even though this is permitted in the class file spec. This transformer
inserts a NOP at the end of any code array that has such an exception
handler.

I think we have the correct behaviour in all cases now: fields will
never override fields. Only non-static methods may override other
methods.

A static member should not override an equivalent member in a superclass
or superinterface. This commit makes us skip the union() calls for
static methods, such that the two disjoint sets are not incorrectly
joined together.

This commit:
* Renames isMethodImmutable to isMethodRenamable and flips the value of
the boolean it outputs accordingly.
* Updates all uses of isMethodRenamable to account for this.
* Makes the internal implementation more similar to isClassRenamable.

This picks up a glGetString(GL_EXTENSIONS) constant.
Don't translate gl calls within the jaggl.opengl class itself. This
causes failures as there are native methods with 0 and 1 suffixes. These
methods don't exist in the OpenGL registry, causing the transformer to
throw an exception.

This fixes a GL_OBJECT_COMPILE_STATUS_ARB constant, but I'm doing
everything else in the same set of enums for consistency.
