0a79d6c1f7 Fix out-of-bounds read in lexer comment/hashbang skipping 
skipSingleLine, skipSingleLineComment, and skipMultiLineComment incremented
the source index and then called peekCharWithoutEOF() without re-checking
eof(), causing a one-byte heap read past the source buffer when the input
ends with a bare \r or a trailing '*'. Guard each follow-up peek with eof().

Fixes #1568

97e8115ab1 Add basics of Chrome Devtools debugger support 
- Use routing table for request dispatch in DebuggerHttpRouter, for
  handling choosing which debugger stack to use based on the http
  upgrade request:
    - DebuggerEscargot for the python debugger and VSCode
    - DebuggerDevtools for connecting to Chrome Devtools
- Parse mesasges with 16bit message size
- Reply to the first few messages chrome sends
- Refactor Debugger:
    - Rename DebuggerRemote to DebuggerEscargot
    - DebuggerEscargot and DebuggerDevtools inherit from
      DebuggerTcp which inherits from Debugger
- Add debugger info to README.md

9819a8de49 Debugger: add dedicated message for VSCode watch 
Processing VSCode watches skips waitForResolvingPendingBreakpoints
(previously having multiple watches in VSC would call this when
processing the first watch, which would process pending messages while
trying to wait for break point changes while in eval mode (not in
waiting mode) and cause and Invalid message error and the closure of the
debgger connection when hitting the second watch message)

Allow '*.mjs' files in the python debugger

Add watches to the python debugger, add test
