This already caught some cases of public members that should have been
private and one case where the inferred type was too specific.

The new system will make it easier to port the deobfuscator to different
revisions.
There are two main changes:
- The addition of a Profile class, which contains a list of excluded
classes, methods and fields, and the maximum obfuscated name length.
It is passed to Transformers that require it with dependency
injection.
- New ClassFilter and MemberFilter infrastructure. The MemberFilter
class adds support for filtering fields and methods based on the
owner and descriptor, in addition to the name. This makes the filters
more precise than the previous system. It also supports globs, which
makes it easy to filter whole groups of classes, fields and methods
in one go.
The Profile class uses a ClassFilter and MemberFilters to
represent the list of excluded classes, methods and fields.
A separate benefit is the addition of a separate entry points filter
to the Profile class. Prior to this commit, many Transformers re-used
the excluded method filter to find entry points, which is less precise
(many of the excluded methods in 550 are not entry points).
Support for filtering methods by owner and descriptor in addition to
name allows the DEFAULT_PUBLIC_CTOR_CLASSES Set in VisibilityTransformer to
be combined with the entry points filter.
In the future it might be desirable to split the excluded method set
into three separate sets:
- One to represent methods that can't be renamed.
- One to represent methods whose signature can't be changed.
- One to represent methods that can't be removed.
