Remove elision of leading wildcard in some filter patterns

Leading wildcards before valid token characters need to
be kept in order to respect the semantic of the filter.
A leading wildcard in such case changes the semantic of
a filter, i.e. two following filters are semantically
different:

    example/abc
    *example/abc

As a result, µBlock.BidiTrieContainer.indexOf() is now
able to deal with a needle of length zero -- which is
what happens in FilterPatternLeft(Ex) with filter
patterns starting with `*` (or `^*`) and followed by
valid token characters (0-9, a-z and %).

For code reviewers

All wasm files in that directory where created by compiling the corresponding wat file using the command (using hntrie.wat/hntrie.wasm as example):

wat2wasm hntrie.wat -o hntrie.wasm

Assuming:

  • The command is executed from within the present directory.

wat2wasm tool

The wat2wasm tool can be downloaded from an official WebAssembly project: https://github.com/WebAssembly/wabt/releases.

wat2wasm tool online

You can also use the following online wat2wasm tool: https://webassembly.github.io/wabt/demo/wat2wasm/.

Just paste the whole content of the wat file to compile into the WAT pane. Click "Download" button to retrieve the resulting wasm file.
