As per https://sourceware.org/bugzilla/show_bug.cgi?id=18146, abidiff
the exit code of abidiff and abicompat is now a bit field that can be
inspected to know if the ABI change reported is incompatible for sure,
or if it needs user review of the output to decide.
This patch also updates the documentation.
* doc/manuals/abicompat.rst: Update documentation for abicompat
exit codes.
* doc/manuals/abidiff.rst: Likewise for abidiff exit codes.
* include/abg-tools-utils.h (enum abidiff_status): Declare new
enum.
(operator{|,&,|=}): Declare new operators for the new enum
abidiff_status.
(abidiff_status_has_error, abidiff_status_has_abi_change)
(abidiff_status_has_incompatible_abi_change): Declare new
functions.
* src/abg-tools-utils.cc (operator{|,&,|=}): Define these new
operators.
(abidiff_status_has_error, abidiff_status_has_abi_change)
(abidiff_status_has_incompatible_abi_change): Define new
functions.
* tests/test-diff-filter.cc (main): Adjust for the new exit code
of abidiff.
* tests/test-diff-suppr.cc (main): Likewise.
* tests/test-abicompat.cc (main): Likewise.
* tools/abicompat.cc (enum abicompat_status): Remove.
(operator{|,&,|=}): Remove these operators for enum
abicompat_status.
(perform_compat_check_in_normal_mode)
(perform_compat_check_in_weak_mode): Return abidiff_status instead
of abicompat_status. Adjust therefore.
(main): Adjust to return abidiff_status now, instead of a just
zero for all non-error cases.
* tools/abidiff.cc (main): Likewise.
