Command Execution: distinguish aborted processes

In some cases, bazel terminates a process, e.g., because an error
was found in some other part of the build. If this happens for
a process called from a Skylark repository rule, we want to abort
the rule here, and not hand control back the to the caller; on
the other hand, we want to give the caller the chance to handle
all other kinds of abnormal termination, as executed commands
might be used to probe for properties of the underlying system.

Unfortunately, we cannot do this distinction perfectly, as for a
process terminated by signal 15, we do not know who sent that signal.
However, handling those cases as aborted should not interfere with
existing uses, and there's always a workaround (like a wrapper
process).

Fixes #7993.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
