placeholder implementation for Proxy
feature option control for proxy feature
add duk_bi_proxy.c to dist/build, add commented out feature option to disable it
add guide entry on DUK_OPT_NO_ES6_PROXY
Proxy placeholder test case (fails for now)
placeholder for proxy 'get'
reject proxy objects as a proxy's handler/target object for sanity
more or less working initial 'get' proxy handler
some proxy tests
proxy 'set'
Proxy handler 'deleteProperty', a bit incorrect now as key is string coerced before proxy call
proxy subset tests for: get, put, deleteProperty
fix proxy deleteProperty handling: key is no longer coerced to string before proxy handler call
proxy deleteProperty test fix
#ifdefs for proxy support in object prop handling
api testcase fixes, invalid index error msg change
downgrade a few FIXMEs
testcase trivia
release note update
fixme note on proxy 'get' behavior
