Don't pay a penalty for it in all GetProperty calls.
Additionally, the storage of properties will eventually move to
cmState, which should only contain state and not logic for policies
like this.
The chaining logic doesn't belong to the container, and the
CMakeInstance pointer doesn't need to be in cmPropertyMap.

Compute deterministic GUIDs that are unique to the build tree by
hashing the path to the build tree with the GUID logical name.
Avoid storing them in the cache, but honor any found there.
This will allow project GUIDs to be reproduced in a fresh build
tree so long as its path is the same as the original, which may
be useful for incremental builds.
3b880a07 cmLocalGenerator: Require a valid cmState::Snapshot in the ctor.
e12afe76 cmState: Host some state from the cmGlobalGenerator.
c7b79aa1 cmGlobalGenerator: Require a cmake instance in ctor.
01e1cd5c cmState: Move snapshot creation to the cmake instance.
Refactor the local generator creation API to accept a
cmState::Snapshot. Adjust MakeLocalGenerator to use the 'current'
snapshot in cases where there is no parent. Create the snapshot
for subdirectories in cmMakefile::AddSubdirectory.
This means that snapshots are now created at the point of extending the tree,
as appropriate, and independently of the cmLocalGenerator and cmMakefile they
represent the state for.
In cmMakefile::PushScope, a copy of the closure of keys initialized
in the parent scope is made. In PopScope, essentially the same copy
is inserted back into the parent. That means a lot of duplication
of strings and a lot of string comparisons. None of it is needed,
because the cmDefinitions keys already provide a canonical
representation of what is initialized.
The removal of the separate container also makes the variable handling
code more easy to reason about in general.
Before this patch, configuring llvm uses 200 KiB for the VarInitStack.
Overall peak memory consumption goes from 35.5 MiB to 35.1 MiB.
Presumably the intention here is to attempt to optimize memory by not
storing what is not needed. However, all keys need to be tracked
anyway to implement initialization tracking, and this special case
gets in the way of simplifying the implementation of that.
This doesn't change any observable effects because values set
to 0 are considered not to exist by the cmDefinitions API.

The backtrace will soon not be implemented in terms of a stack of
cmListFileContext objects. Keep the cmListFileContext in the API
for convenience for now.
The lexical scope counting added by commit v3.2.0-rc1~332^2~1 (Track
nested loop levels in CMake language with a stack of counters,
2014-11-18) forgot to account for scopes popped by error messages about
unclosed scopes. Teach the error handler to pop the lexical scope it
reports as unclosed. Re-order the lexical scope RAII object to be
inside the variable scope RAII object scope so that the lexical scope
is fully closed before we check assertions about variable scopes.
Extend the RunCMake.Syntax test with a case covering this.

Since commit 80909041 (cmMakefile: Disable copy constructor, 2015-04-18)
the only call to cmMakefile::Initialize is in one constructor. Inline
it and drop the separate method.
In commit 86f3cd0f (cmMakefile: Require the localGenerator in the
constructor, 2015-04-27) we added use of GetDefinition to the
Initialize method. Set SuppressWatches before calling this method
since GetDefinition checks it.

This reverts commit 242c3966 (add_custom_command: Diagnose
MAIN_DEPENDENCY limitation, 2015-03-09) and the follow up commit
b372a99a (UseSWIG: Do not use MAIN_DEPENDENCY on custom commands,
2015-03-26).
I misdiagnosed the underlying issue that prompted creation of policy CMP0057.
The actual issue surfaces when a single custom command's MAIN_DEPENDENCY
is listed in more than one target; this issue will have to be addressed
independently.
The purpose of the stack is to allow access only to the top of it. Access
to items which are not at the top is needed, so cmDefinitions objects
get a Parent pointer.
The existence of the Parent pointer is a workaround for the inappropriate
use of stack in the first place. Remove it now.
Construct the final list directly in a named return value. Use
a single set to track bindings already found.

3a68c323 cmMakefile: Fix wrong parameter names.
They are maintained as containing the same content as the 'home'
directories, but they are never read from.
Fix some comments and help strings which confused the two by
name. They actually mean what is called CMAKE_SOURCE_DIR in
cmake code.
Call the Internal method with equivalent parameters, passing a null first
argument.
A duplicate path computation exists inside the external_in condition now,
but that is harmless at this point.
Because all external callers of this method pass a null first
parameter, this change has no effect for them.
This also makes it obvious that the CMAKE_PARENT_LIST_FILE is set to
the name of the file being read itself for CMakeLists.txt files,
which may not make any sense.
Global properties are already global in scope, so remove the
overload for specifying it and port users of the API.
The call from cmMakefile::GetProperty can be simplified because
the scope is only used during chaining, and there is no further
chaining after processing global properties.
At this point, it is an interface to the cache. It will be extended
to be a universal interface for access to and manipulation of
configuration-time data (defintions, properties on targets,
directories, source files etc).
This will allow porting all command implementations away
from the cmMakefile and cmTarget classes, and result in something
more-purely related to configuration-time processing of cmake
commands. That should serve at least the following goals:
* Split the CMake implementation more definitively into three
stages: Configuration, computation and generation, and be able to
implement each optimally for memory access patterns etc.
* Make better IDE integration possible by making more configuration
data available.
* Make it possiblte to use a smaller library than CMakeLib.a in
cpack and ctest, resulting in smaller executables.
* Make it possible to run the configure step multiple times in
the same CMake run (#14539).
Manage its lifetime in the cmake class, and add a convenience accessor
to cmMakefile.
This topic was never tested without some follow-up commits. The
GetCacheEntryValue API returns a pointer to memory freed on return.
It will have to be revised along with the rest of the original topic.
Add policy CMP0059 to cover this change. The property has been
deprecated since CMake 2.4 anyway.
This will help clean up cmMakefile -- the DefineFlagsOrig member should
not need to exist.
