cmDefinitions: Don't store parent lookups

When looking up scopes, it is faster to not store the lookup locally to
keep the maps smaller and avoid extra allocations and rebalancing.
cmDefinitions: Avoid a find-then-insert when setting variables

Searching the map is not necessary.
cmDefinitions: Use a hashmap for faster checks

The hash map is much faster at checking that the map won't have what
we're looking for so that we can just go to the parent scope instead.

Encoding:  Change to only set LC_CTYPE to fix encoding issues with libarchive.

Changing all categories with LC_ALL causes test failures in some locales.
For example, in some locales, the decimal characer could be a comma instead of period.
cmake: Fix read-after-free while checking command-line arguments

Since commit v2.8.12~300^2~1 (CLI: Suppress the unused warning if the
key value pair is cached, 2013-05-16), cmake::SetCacheArgs saves a
cachedValue pointer and may cause the memory to be freed (by setting the
cache entry) before reading it again.  Fix this by saving the old value
in a separate string.
VS: Move VS-only API out of cmGlobalGenerator

Move the IsDependedOn method to cmGlobalVisualStudio7Generator
since that is the only caller.
CTest: Add Jacoco Coverage functionality

Add the ability to parse the XML output of the Jacoco tool.

Jacoco (www.eclemma.org/jacoco) is a Java coverage tool.
Add and integrate a class for the parser and
include a test which utilizes the new parser.
VS: Fix subproject .sln dependencies on custom targets

Each project listed in a .sln must be marked (or not) as part of the
"default build" for each configuration.  For targets created by the
add_custom_target() command we add them to the default build if they
are not excluded in some way or if another target depends on them.
In the top-level .sln, a custom target is excluded if it is not
created with the ALL option to add_custom_target.  In subdirectory
.sln files, a target may also be excluded if it is not within the
directory and is brought into the solution only due to a dependency
from another target in the solution.

Fix the "IsPartOfDefaultBuild" and "IsDependedOn" methods to check
every target to be included in the .sln for a dependency on the
custom target.  Otherwise transitive dependencies through targets
not in the current subdirectory will not be considered.

Extend the SubProject test with a custom target to cover this case.

Help: Mention INTERFACE_SOURCES as settable for INTERFACE libs

The add_library(INTERFACE) and Interface Libraries documentation
list all the INTERFACE_* properties and target_* commands that
can be used to define the interface.  Add INTERFACE_SOURCES
and target_sources() to these lists for completeness.
Help: Organize Binary Targets section of cmake-buildsystem.7

Libraries.
Help: Update style guide to use section headers for command signatures

In order to be able to link to specific command signatures we need to
use a section header instead of a horizontal separator.
