The regeneration was made with Ubuntu automake which has this runstatedir
additional variable, compared to the usual automake.

Libsframe was missing AC_CANONICAL_TARGET, meaning that --target was
ignored. This could prevent libsframe.a to be installed in some cases,
the host fetching its canonical value while the target isn't. Both
having a different value, INSTALL_LIBBFD would be false.

Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.

Define an empty base version LIBSFRAME_0.0 and add all symbols to
version LIBSFRAME_1.0.
The previous release of libsframe (libsframe.so.0) did not have
versioned symbols. Adding a libsframe.ver file so that future releases
of the library (and its consumers) can manage the changes better.
For Solaris ld, use -M mapfile command line option. libsframe does not
restrict the set of exported symbols, so at this time there is no need
to fall back on the libtool's -export-symbols option for platforms where
some other linker (with a different command line option for symbol
versioning) may be used.

* Makefile.am: Use symbol versioning for libsframe.

* configure: Check for Solaris ld.
* configure.ac: Regenerated.
* libsframe.ver: New file.

lisbframe was first released with Bintuils 2.40. As the library
evolves, some changes will break the ABI. Add library versioning for
users to manage these changes.
For the next release of the library (libsframe.so.1), incompatible ABI
changes are planned. These will include:
- Deprecation of some APIs, like sframe_get_funcdesc_with_addr (), and
- Change in the contract of some APIs (e.g., return type, behavior).
In libtool-version, set the current to 1 to prepare for the upcoming
release. Reset revision and age to 0.
Add libtool-version file to EXTRA_DIST.

* Makefile.am: Use libtool versioning.
* Makefile.in: Regenerated.
* libtool-version: New file.

Add a new test plt-findfre-1 to ensure lookup of SFrame stack trace
information for pltN entries is correct.
In this test, a dummy SFrame FDE of type SFRAME_FDE_TYPE_PCMASK is
created. The size of the 'function code block' covered by the SFrame
FDE is equivalent to 5 pltN entries of 16 bytes each.
The test first looks up SFrame FREs for some addresses in the first pltN
entry, followed by lookups for some addresses in the fourth pltN entry.

sframe_get_funcdesc_with_addr API is currently used internally by the
sframe_find_fre ().
In this test, we create three dummy SFrame FDEs with 4 FREs each. Then,
we use few negative tests to lookup FREs with PCs not in the range of
PCs covered by the FDEs, ensuring graceful return from
sframe_get_funcdesc_with_addr in all cases. Some positive tests are
also added that exercise further scenarios as well.

libsframe provides an API to find the FRE associated with a given PC in
the program. This patch adds a direct test of this API.
In this test, we create two dummy SFrame FDEs with 4 FREs each. Then we
test that sframe_find_fre () works for the first, second, third and the
last FRE from one of the FDEs. Such a test ensures better regression
testing for the sframe_find_fre () function which is going to be the
bread and butter of an SFrame based stack tracer.

The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

libsframe is a library that allows you to:
- decode a .sframe section
- probe and inspect a .sframe section
- encode (and eventually write) a .sframe section.
This library is currently being used by the linker, readelf, objdump.
This library will also be used by the SFrame unwinder which is still
to be upstream'd.
The file include/sframe-api.h defines the user-facing APIs for decoding,
encoding and probing .sframe sections. A set of error codes together
with their error message strings are also defined.
Endian flipping is performed automatically at read and write time, if
cross-endianness is detected.
