The Ninja and Makefile generators were adding a space to the value both
before and after expanding rule variables. Only the latter is needed.
While at it, revise some outdated comments since the rule variable
expansion is no longer responsible for inserting the launcher.

Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.

Ninja runs just one command line for every build statement, so the Ninja
generator needs to `&&`-chain multiple commands together into one long
string. For long custom command sequences this can exceed the maximum
command-line length for the operating system. In such cases, write the
commands out to a script instead, and then run the script from Ninja's
one command line.

This enables configuration of build parallelism with the Ninja generator by
passing arguments on the command line to CMake. For example,
cmake \
'-DCMAKE_JOB_POOLS:STRING=compile=5;link=2' \
-DCMAKE_JOB_POOL_COMPILE:STRING=compile \
-DCMAKE_JOB_POOL_LINK:STRING=link \
~/src/MyProject
Add an index to Change cmLocalGenerator::GeneratorTargets for faster lookup by
name.
Also changed a bunch of uses of cmLocalGenerator::GetGeneratorTargets() to take
const references instead of copying the vector.
Represent generator targets as a map (name -> target) to make name lookups more
efficient instead of looping through the entire vector to find the desired one.
Copy the value to our `ConfigName` member on construction to ensure it
is available even to code paths that run before `Generate`. We once
needed to delay this lookup until `Generate` because the local
generators were at one time created before `Configure`. Now they are
created at generate time which is late enough to expect
`CMAKE_BUILD_TYPE` to be available.
Without this, `cmGlobalUnixMakefileGenerator3::WriteConvenienceRules`
causes use of `ConfigName` before it is populated which breaks use of
source files that depend on the `$<CONFIG>` generator expression.

Add `CMAKE_SYSROOT_COMPILE` and `CMAKE_SYSROOT_LINK` variables to as
operation-specific alternatives to `CMAKE_SYSROOT`. This will be useful
for Android NDKs that compile and link with different sysroot values
(e.g. `r14` with unified headers).

Put commands that contain `||` into brackets to avoid early abort of
execution by `cmd.exe` because `||` has higher precedence than `&&` in
`cmd.exe`.
Add test to check for command execution after `||` as part of a
parameter and as command separator.

Previously, given two libraries, X and Y where X depends on Y, all
object compilations of X would require the Y library to have been linked
before being compiled. This is not necessary and can instead be loosened
such that object compilations of X only depend on the order-only
dependencies of Y to be completed. This is to ensure that generated
sources, headers, custom commands, etc. are completed before X starts to
compile its objects.
This should help build performance in projects with many libraries which
cause a deep library dependency chain. Previously, a library at the
bottom would not start compilation until after all other libraries
completed, but now only its link step needs to wait and its compilation
jobs can be run in parallel with other tasks.
Fixes: #15555
Add a factory function to cmLocalGenerator so that variableMappings can
be provided from it, and so that Ninja can always have a hard-coded
TargetImpLib.
The rule replacement API should not really be in cmLocalGenerator, but
it was historically, and this coupled many other things together here
too, such as output conversion. Make the output converter a parameter
so that rule replacement can be removed from cmLocalGenerator.
This one is not like the others as it doesn't participate in
substitutions. Keep ExpandRuleVariables doing only one thing and make
callers responsible for inserting a launcher prefix, simplifying the
code all-around.
Remove now-obsolete InsertRuleLauncher method.
CMake has several classes which have too many responsibilities.
cmLocalGenerator is one of them. Start to extract the link line
computation. Create generator-specific implementations of the interface
to account for generator-specific behavior.
Unfortunately MSVC60 has different behavior to everything else and CMake
still generates makefiles for it. Isolate it with MSVC60-specific
names.
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.

error on other generators.
