This allows us to skip 'git cl format' for histograms.xml, which in
turn allows us to issue a presubmit error rather than a warning when
that file is malformatted, without running the formatting code twice.
The formatter is somewhat slow for this file, so it's helpful to avoid
duplicating that work.

There are some usecases where it is simpler to pass path to the 
cache by an environment variable or command-line argument 
than to modify the gclient config file.

With this change:

 * GCLIENT_CACHE_DIR environment variable overrides cache_dir variable
   from .gclient file.

 * --cache-dir argument moved from gclient config to all gclient
   commands and overrides values from .gclient file and environment
   variable.

Otherwise it'd get stringified to "None" and make resulting DEPS invalid.

In theory we could properly serialize them to None,
but it's simpler to just skip them, since they do not affect resulting checkout.

This is part of preparation for gclient flatten, conditions,
and improving internal gclient workflows.

This also ensures variables have consistent values in the entire checkout,
unlike the current situation where different DEPS files can use different
values for the same variable.

We override instead of erroring out, since otherwise commonly used dependencies
such as buildtools wuld have to be rolled simultaneously in unrelated projects,
say v8 and native_client.

Another reason for overriding are possible future use cases such as is_chromium_build,
which could be set to false e.g. in v8, but chromium DEPS would override it to true.

Before C++11, we were using a hack to disable copy constructors or copy
assignment by declaring the methods private and not implementing them.
This hack required the respective macros to be placed in the private:
declarations of a class.
The macros have switched to use the C++11 "= delete" syntax some time
ago in both v8 and chromium:

https://codereview.chromium.org/2017213002

Also the comments are now updated, since the macros do not need to be
in the private: declarations any more:

https://chromium-review.googlesource.com/c/578027

This change removes the presubmit check that checked that the
macros are only used in the private declarations.

This is a cherry-pick from https://github.com/google/styleguide/pull/265.
