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.
Create a SPHINX_FLAGS cache entry that users can populate with
command-line flags for sphinx-build. Add an option to the
bootstrap script to populate it up front.

In commit 74de9a73 (cmGlobalGenerator: Delegate storage of enabled
languages to cmState, 2015-04-11) the original LanguageEnabled
member of cmGlobalGenerator was left behind by mistake. One use
of it in EnableLanguagesFromGenerator (for try_compile) was left,
but the member is not populated anymore. Drop the member and
teach EnableLanguagesFromGenerator to copy the list of enabled
languages from one cmState to the other.

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.

The previous example for CMP0054 did not show how critical the policy is
since the result is the same in both cases (NEW and OLD behavior).
Instead show an example when the policy does make a difference.
Add sections to the cmake-buildsystem(7) manual and cross-reference
them with relevant variables and target properties. This avoids
duplicating the information and allows it to be more detailed.
46f6a5f4 cmState: Store the Current directories.
3a041c59 Introduce cmState::Snapshot.
ae6c8a9d cmState: Store the Source and Binary directories.
86f3cd0f cmMakefile: Require the localGenerator in the constructor.
a48aebcb cmLocalGenerator: Require a parent in the constructor.
e4c78b37 cmMakefile: Inline SetHome* methods into last remaining caller.
410f39a4 cmMakefile: Delegate storage of Home dirs to the cmake class.
Many projects put their project() call first, but the actions taken
by this command can be influenced by policies and other information
set by a call to cmake_minimum_required. Document in each of these
two commands that cmake_minimum_required should be called first.
