TestByteBuffer*Stream: Reduce mmap load on poor OSX mini test machine to reduce test time (was: > 10 min)

Bug 1134 - Pass ASTLocationTag to all types, used for GlueGenException

Enhances semantic exception in code generation
by adding the AST location of the type or function declaration.

Bug 1134 - Handle Opaque fields in structs; Print struct field name in apidoc of getter/setter

Bug 1134 - Fix IntType: Add getCName(..) for proper C-type code; Fix its newCVVariant(..), don't pass given cv-attr as typedef

Add getCName(..) for proper C-type code
  - Add 'unsigned ' if not typedef and is unsigned.

  - Allows removal of special case in CMethodBindingEmitter

  - Fixes ProcAddressCMethodBindingEmitter typedef emission
    and removes clang warnings, caused by this (many).

Fix its newCVVariant(..), don't pass given cv-attr as typedef
  - Proper delegation of 'const', regression of prev. commits

Fix Type.getDebugString() comma separation

Bug 1134 - Use ASTLocationTag in Logging (PCPP, Emitter); Refine ASTLocationTag log/exception formatting.

Since commit eca019cdea4017227e951d8a9eb30cb34fca4a07, we have ASTLocationTag available.
Hence use it for all logging purposes and emit a standard compiler output,
which shall be parsable by other tools.

Bug 1134 - Logging's formatter now takes care of Type -> getDebugString() when desired, not at 'log' call

Removes load to assemble the getDebugString() of Type and JavaType
when invoking log function. Note: the log may be skipped if log-level is not reached.

Bug 1134 - Make ASTLocusTag's text optional

Bug 1134 - Fix IntType 'unsigned'; Type: Use copy-ctor instead of Clonable, ..

- Fix IntType 'unsigned'
  - Need to handle 'unsigned' for typedef and !typedef,
    when exposing 'unsigned' for code emission.
  - Consider IntType.typedefUnsigned in hash/equals

- Type: Use copy-ctor instead of Clonable enhancing strong typing.
  - add 'Type clone(final ASTLocusTag newLoc)'

- Consider Type.typedefCVAttributes in hash/equals

Bug 1134 - Fix aliased typedef struct emission

- Code regarding 'aliased typedef struct' is tagged in JavaEmitter and HeaderParser:
  'NOTE: Struct Name Resolution (JavaEmitter, HeaderParser)'

  Prefers containing cstruct typedef pointer
  if available _and_ if cstruct is _not_ a typedef!

- Removed: 'HeaderParser.resolveAnonCompound(..)' no more required,
  since CompoundType always sets its name!
  Commit cf9f28cf249393f42d7d2835775521dfadee6b92

- JavaEmitter.emitStruct:
  - Regard above 'aliased typedef struct' NOTE

- JavaEmitter.typeToJavaType:
  - Regard above 'aliased typedef struct' NOTE

- ReferencedStructs
  - Drop duplicate CompoundType instances of same name.
    This can happen due to const/volatile and ASTLocusTag variants.

Bug 1134 - Fix CMethodBindingEmitter return type '_res' qualifiers

We cannot have the local variable holding the return type 'const'
and assign a value to it later.

Bug 1134 - ProcAddressCMethodBindingEmitter: Use available 'ProcAddrTypedef' for type validation w/ local generated variant (robustness)

ProcAddressCMethodBindingEmitter code regarding having the public 'ProcAddrTypedef' (from input header)
was simply broken, since it always used the local generated 'ProcAddrTypedef',
if 'ProcAddrTypedef' was forced. Hence the public 'ProcAddrTypedef' was ignored in most cases.

ProcAddressCMethodBindingEmitter's semantic changed from:
  needsLocalTypedef -> hasProcAddrTypedef

New Code generation:
- always generated the local 'ProcAddrTypedef'
- if hasProcAddrTypedef, use public 'ProcAddrTypedef' for return type variable
- cast local 'ProcAddrTypedef' to public 'ProcAddrTypedef',
  which renders the native compiler to validate the local and public types.

Bug 1134 - Fix CMethodBindingEmitter return type '_res' qualifiers (part 2)

Commit 414a0146660cadd35d5ae270f7f819717e9c7374
removed the const/volatile of the local return variable.

This change also casts the function calling result
to the same - hence removing a possible c-compiler warning
of dropping qualifier const.

Bug 1134 - In case of 'undefined type' throw a semantic GlueGenException instead of an NPE

Bug 1134 - Add ASTLocusTagProvider for Define and fix newline in c-parser (Expose source location for log/error messages)

Bug 1134 - Refine err/log message of 'previous definition is here'
