v4.103.1: corrected 4.103 release

v4.103.0 was created against the wrong commit; no current HHVM meets its' constraints, so shouldn't present problems.

v4.103: cache location change, support and require HHVM 4.103

This release:

• stops creating foo.hack.parser-cache files in the same directory as foo.hack; instead, they are created in $REPO_ROOT/.var/hhvm/hhast. This provides a cleaner experience for many IDEs and tools, but may need an updated .gitignore
• supports and requires HHVM and Hack 4.103

v4.102: support and require HHVM 4.102

Also fixes a false positive in UnusedVariableLinter (#354).

v4.101: support HHVM/Hack v4.101

This release supports HHVM 4.94-4.101; there are no changes since 4.100 except for compatibility with the next HHVM release.

v4.100.0: support HHVM 4.100, new linters, fixes

• This release is partially backwards compatible. HHVM 4.94+ is still supported, however there's a minor breaking change in HHAST's API—the following classes gained a new constructor argument:
  • ClosureParameterTypeSpecifier
  • ClosureTypeSpecifier
• New linters:
  • NoNewlineAtStartOfControlFlowBlockLinter
  • DontHaveTwoEmptyLinesInARowLinter
• Removed linters (both of these are typechecker errors in all supported HHVM versions):
  • MethodCallOnConstructorLinter
  • NoBasicAssignmentFunctionParameterLinter
• Fixes:
  • UnusedParameterLinter and UnusedVariableLinter now better handle lambda functions (#341)
  • DontAwaitInALoopLinter no longer emits an error when await is used in a return or throw statement inside a loop (#280)
  • NoEmptyStatementLinter now correctly handless braceless conditionals/loops (#146)
  • Calling var_dump on any HHAST node now provides more useful output (#352)
• Methods like getDescendantsOfType on HHAST nodes now have alternatives (e.g. getDescendantsByType) that use reified generics instead of classname arguments, e.g. $body->getDescendantsByType<LambdaExpression>()

Thanks @lexidor for contributing most of the changes in this HHAST release!
