1. Add a repeated Configuration field to CqueryResult, and fill in the
checksum, platform, and mnemonic fields.
2. Add a configuration_id field to ConfiguredTarget, and deprecate the existing
configuration field in ConfiguredTarget. The configuration_id field is an index
that points to the Configuration message stored in CqueryResult, following the
same pattern as ActionGraphContainer. This avoids duplicating the same
Configuration message for each ConfiguredTarget.
RELNOTES: Include more information about configurations in cquery proto
formatted output. This deprecates the configuration field of
AnalysisProtosV2.ConfiguredTarget, and adds a new field, configuration_id, to
be used instead.

Adds back providers to cc_shared_library bzl file in rules_cc until TF is using
bazel from head and can use the builtin cc_shared_library version.

Eventually, when we are ready to pull out all the other rules to an external
repository cc_shared_library will be moved with the others: cc_library,
cc_binary,...

The cc_shared_library_permissions mechanism was introduced to add control over
which cc_shared_libraries can export a given cc_library. If the repo is big
enough, the owner of a cc_library might want to prevent someone else in a
different package making their library part of the ABI of a public shared
library because that makes it harder to change the cc_library. This does not
apply accross repositories because a dependant repository can overwrite
anything from a repository dependency anyway.
However, it is becoming more apparent than even though this mechanism should
exist, it should not be enabled by default since most people don't need it. To
enable it pass the flag --//examples:enable_permissions_check=True.

--//examples:incompatible_link_once=False[default = False]
When True, it will be an error to link the same library more than once
unless it has the tag LINKABLE_MORE_THAN_ONCE
--//examples:experimental_debug=True[default = False]
When True, it will generate files listing the exports of each cc_shared_library
and which libraries are linked to it statically.

Changes in this CL:
1. 'exports' attribute renamed to roots
2. Removed restrictions for exporting a rule in a different repository
3. Kept restrictions for rules in the same repository but not in the same
package or subpackages
4. To get around restrictions, instead of the exported_by tag, one can use the
cc_shared_library_permissions rule
5. Added exports_filter that will match libraries in the transitive closure of
a root. Anything matched by the exports_filter will also be exported.
Restrictions as in 4. still apply.

The syntax now matches visibility's. This is less confusing than
before, we now have:
- targets like //foo, //foo:foo or //foo:bar
- same package match like //foo:__pkg__
- subpackages like //foo:__subpackages__

The --experimental_cc_shared_library used to block API methods
that were needed in the cc_shared_library implementation. However, these
methods have been made freely available to everyone so that people can start
migrating to the new API.
With that change, the cc_shared_library has become free to use unless we block
it with the method call added in this CL.

The same command line can be obtained with the attributes
user_link_flags and additional_linker_inputs used together.
In the first design iterations of cc_shared_library it was decided to have the
visibility_file attribute so that a cc_shared_library could be used for many
different platforms smoothly.
For this to work the visibility file would have had to be platform neutral and
then Bazel would have had to write a visibility file specific for each
platform, e.g. the version script for Unix and the exports map for Windows.
However, in the last approved design it was decided not to have Bazel get in
the business of understanding symbols and automatically writing export maps.
With this approach, it then became necessary for people to use selects() in the
visibility_file attribute depending on the platform that the file was for.
Since we have added a new way to add files with the attribute
additional_linker_inputs and we need selects() anyway,
it doesn't make sense to keep the visibility_file attribute, the
same can be achieved with selects in the other two attributes mentioned.
In any case, if this can be made more ergonomic in the future, we can do so.
However, removing this attribute after flipping the experimental flag would be
an incompatible change.

Before dynamic lib dependencies of cc_shared_library were always linked at the
end. Now for creating the command line we respect the topological order that
would be given when getting the libs from the dependency graph created by the
cc_libraries.

Any library should be exportable by any cc_shared_library target regardless of whether the cc_shared_library target is in the same package or a parent package as long as the library author gives permission.
The library author can now do this by writing tags=["exported_by=//foo,//baz"].

For now we will restrict allowed exports to the same package. At the same time
static_deps should be used to take into account what should be linked into a
shared library.

This is in preparation to renaming linked_statically_by to exported_by. The attribute linked_statically_by became redundant in a previous CL that added the static_deps attribute and made libraries in exports be linked statically automatically.

This removes the need for linked_statically_by, although both attributes work for now. The attribute linked_statically_by will disappear from cc_library and instead we will add exported_by which will allow library authors to retain the power of deciding who exports their library.
When a library is linked statically by more than one shared library and this library was only supposed to be linked once, i.e. it contains static initializers, then Bazel will give an error.
