Since all these help text strings are marked for translation, apply the fixes
to translation strings as well, this helps to avoid translations becoming fuzzy.

We don't know sizeof(pid_t) as it's not specified in any standard. In
order to still print it, we cast to long long, the largest integer type
we can easily print.

Rename version.c so that the implementation is called after the header
and the header doesn't clash with the toplevel version.h. print_version
depends on argp and is only used in the tools.

fedorahosted used to be our home, but we are now hosted at sourceware.
Change the elfutils project home to http://elfutils.org/
Point hosted services (email, release, git, bug tracker and web pages)
to https://sourceware.org/elfutils/
Move design notes from README to NOTES.
Add URLs for home, releases, bugs, git and mailinglist to README.
Make the --version output of all tools the same by using a common
print_version function and update the publicly shown copyright holder
to the elfutils developers.

Using dwarf_getscopes_die we can get all scopes that make up the current
subprogram representing an address. Using the call_file/line/column
attributes we can also show the source locations of these "inlined" calls.
Includes a test that shows that when DWARF debuginfo is available all
inlined function call frames and their source location can be shown.

Make -n default just 256 frames, 2048 was too big. Also Document magic

the actual source line we report with -s for a frame address.

Rewrite __libdwfl_attach_state_for_pid and __libdwfl_attach_state_for_core
as public functions and don't call them from dwfl_linux_proc_report and
dwfl_core_file_report anymore. This lets the user attach state explicitly
independ from how the dwfl modules have been reported. Since attaching
state is an explicit action now the error can be returned directly and we
don't need to keep track of process_attach_error. dwfl_linux_proc_attach
lets the user can tell libdwfl whether caller takes care of ptrace
attaching and stopping the threads under inspection, or whether the
callback needs to take care of that and detaching again.

Use to list modules detected for process or core file by stack program
and to see build-ids and which main elf and debug files were recognized
by libdwfl callbacks.

Check up front whether we attached correctly, if not error out. Make sure
callbacks report -1 only on real errors and DWARF_CB_ABORT if exiting early
(but not in error). Handle all errors from frame callback in print_frames
after printing of good frames. Print as much information as possible like
tid, address and module name if known with error messages. Only exit with
exit code zero if everything went fine. Exit with error code one if there
were any non-fatal errors. Exit with error code two if no frames could be
printed or a fatal error occurred.

Resolving addresses to function symbol names can be expensive. Use -q
to only print addresses (use together with --build-id to process later).
Demangle names by default, but add the -r option to not demangle and
show the raw names.

We were using dwfl_standard_argp but trying to add our own and substract
some options from it. dwfl_standard_argp also handles kernel, modules,
executables without state and process maps that stack doesn't support.
That made argp parsing somewhat ugly and meant our --help and --usage
didn't really match. Just handle the dwfl_standard_argp options we do
want directly ('-p', '--core', '-e' and '--debuginfo-path'). That way
we can also do sanity checking on the options given.

Limit the number of frames printed per thread (defaults to 64) and resolve
addresses to names, modules and source after unwinding so the thread is
only stopped for the minimum time needed to do the actual unwinding. The
thread doesn't need to wait for the lookups and printing of information.

dwfl_getthread_frames is a convenience function for when the user is only
interested in one specific thread id of a process. It can be implemented by
a simple wrapper function that removes an extra callback layer just to
filter on thread id. But it also provides an optimized path to getting
access to just one particular Dwfl_Thread of the Dwfl process by providing
and (optional) new callback for the state provider. The pid_thread_callbacks
now provide an (optional) pid_getthread that doesn't need to travers all
threads anymore. Which is implemented for the linux-pid-attach provider.
stack now uses this to implement a new '-1' option that shows just one
specific thread of a process.

This patch adds the module and source file information to the
each stack trace line. `-m' is for module file information
and `-s' is for source file information. `-v' is for both and more.
This is based on private discussion with Jan Kratochvil
<jan.kratochvil@redhat.com>.
In v2 patch, `-s' and `-m' options are introduced instead
of using `-v' repeatedly as suggested by Mark Wielaard <mjw@redhat.com>.
In v3 patch `-a' is added as extra option and source lines are
printed on their own line.
