changed resolution order: first priority is 'local extensions; members; nonlocal extensions', than by implicit receivers (before was vice versa)

 It's important to be aware of what stream the messages will be written to, so such a default implementation is harmful

We used to have a triple (errorStream, messageRenderer, verbose) to represent the error reporting strategy.
 Now we have a single MessageCollector abstraction for this.
 As the MessageCollector abstraction was extracted, the need to CompilerMessageLocation and CompilerMessageSeverity arose, too.

Got rid of CompileSession class: this class shouldn't have had any objects, now it is transformed into KotlinToJVMBytecodeCompiler

* assert runtime implementations from JetStandard* are not loaded
  by JavaDescriptorResolver
* fix wrong @JetMethod in jet.Iterator
* fix jet.Iterator ns was created
* fix incorrect number of functions and tuples in JetStandardClasses
* added TODO about inconsisten Tuple class

JetCoreEnvironment encapsulates a project (in the IDEA sense), so the classpath and sources lie in its area of responsibility

This reverts commit 18170a0b.

Holds reference to runtime.jar and jdk-headers.jar. Paths to these
jars are no longer hardcoded.

Many tests now compile runtime before execution. Because of this:
* Single test invocation is significantly slower now for some tests
* This can be fixed by making tests independent from runtime (this
must be done anyway)

Some tests still depend on runtime.jar built by "ant dist", this
is to be fixed.

(will be used later)

 #KT-1666 fixed

include jdk-headers, do not include runtime

used in JetTypeMapper in JetTypeMapper

* MapTypeMode contains no information not needed by JetTypeMapper
* MapTypeMode has separate VALUE and IMPL values that are needed to compile builtins

Delete analyzer*WithCache methods from AnalyzerFacadeForJVM.
Introduce JsModuleDetector.
Move AnalyzerFacadeWithCache to idea module. Make it static, make it acquire facade through AnalyzerFacadeProvider.

(Rename problem was caused because of invalid reference to file from package. Fix contains:
 - Change structure of references in package expression - last part is also a reference now
 - Resolve packages to expression but not to files)

  #KT-1702 fixed

* do not include anything when compiling builtins
* do not include kotlin-runtime and jdk-headers when compiling jdk-headers
