Removed unused file_system_manager dependency

|

Removed superfluous "OS" env var

... by using the fully declared rules-cc repository and
feeding ed from stdin.
|
|
... by explicitly specifying the protobuf repository and
using just-import-git to import the rules-cc repository.
Furthermore, protobuf's subdir "examples" is used directly
and all targets are created in the top-level module.
|
|
... by adding some remarks and creating all tests in module
"tests".

The value of --just option should be used as-is,
as it might be a var in PATH. The `execvp` call will handle this.
The Python script and man page have been updated accrodingly.

... given that binaries now only have "private-proto" (as there
are no public dependencies of a binary anyway). While there, also
hint on the script for git imports, to simplify the setup of
the example.

... on parts a first-time reader might (and actually did) stumble upon.

Compared to the previous commit, the action graphs for just
and its unit tests are unchanged.
- Git hash of action graph for ["",""]:
c6e75f17abd7ffaab6ff9bb725ad67ec0bf6c973
- Git hash of action graph for ["test/buildtool","TESTS"]:
8063dfb3dd7daa9ae01d95c177e14946f785c57e
Refactor:
- "local cflags" to "private-cflags"
- "local defines" to "private-defines"
- "link externals" to "private-ldflags"
- "deps" to "private-deps" for (test) binaries
- "proto" to "private-proto" for binaries
Improvements:
- consistent variable declaration order:
OS, ARCH, HOST_ARCH, TARGET_ARCH,
CC, CXX, CFLAGS, CXXFLAGS, ADD_CFLAGS, ADD_CXXFLAGS,
AR, ENV, PATH
- use fields close to their definition (in RULES)
- use common expression for binaries and test binaries
- split expression "flags" and "compiler"
... to separate ones for CC and CXX.
- rename "transition" to "deps-transition"
... to avoid conflicts with other transitions.
- support "defaults-transition" for CC expressions
Implement:
- "cflags" for libraries
- "private-cflags" for (test) binaries
- "private-defines" for test binaries
- "private-ldflags" for test binaries
- (public) "defines" for libraries

... in favor of the "tree" built-in rule.
|
|
... which is required for cross-compilation, e.g., clang's
`-target` option.
|
|
|
|
... so that for every construct supported in rules there is
an analogous one as a built-in rule to allow ad-hoc constructions
without having to write a rule (even though writing a rule is
recommended for everything occuring more than once):
- the "generic" rule allows an ad-hoc ACTION,
- the "file_gen" rule allows an ad-hoc BLOB,
- the "tree" rule allows an an ad-hoc TREE, and
- the "configure" rule allows an ad-hoc configuration transition.

The dependencies requested in order to read their "outs" or
"runfiles" also contribute to the effective configuration.
|
|
|
|
|
|
If norc options is given then no checks for the rc_path (e.g.,
whether it points to a file or not) should even be considered.

... assuming this repo already uses just and has a multi-repository
configuration committed. In the import, transitive dependencies, as
well as repositories serving as layers, are taken into account, and
"file" repositories are rewritten to be subdirs of the repository
imported. The imported repositories are renamed to reflect the
repository pulling them in, extending the name appropriately to
avoid conflicts. This renaming is reflected in the bindings and
layer references of the imported repositories as well.
In this simple version, no automatic deduplication of imported
repositories to already existing repositories is made, but the
user can specify that certain foreign repositories should not be
imported and mapped to already present repositories.
