Trust AC_SYS_LARGEFILE to provide large file support
AC_SYS_LARGEFILE defines _FILE_OFFSET_BITS in config.h if needed for
LFS, and this automatically maps things like open to open64. But quite
a few places used explicit 64-bit names, which won't work on platforms
like FreeBSD where off_t is always 64-bit and there are no foo64 names.
It's better to just trust that AC_SYS_LARGEFILE is doing it correctly.
But we can verify this too, as some file could easily forget to include
config.h. The new tests/run-lfs-symbols.sh checks all build targets
against lfs-symbols (taken from lintian) to make sure everything was
implicitly mapped to 64-bit variants when _FILE_OFFSET_BITS is set.

libdwfl: Make dwfl_linux_proc_attach work even without any Dwfl_Modules.
dwfl_linux_proc_attach depended on a Dwfl_Module with the correct
ELF header already being available. That isn't really necessary since
when we attach we have the main exe ELF file available. Just use that
to make dwfl_linux_proc_attach always work.

Support note NT_FILE for locating files.
Martin Milata:
------------------------------------------------------------------------------
RFE: dwfl_core_file_report: use NT_FILE core note if the link_map chain is broken
https://bugzilla.redhat.com/show_bug.cgi?id=1129777
The dwfl_core_file_report function follows dynamic linker's link_map chain in
order to determine the shared libraries used by the executable. As this data
structure is located in writable memory it can be overwritten by garbage, which
is sometimes the case.
https://github.com/abrt/satyr/issues/127#issuecomment-46957546
Since version 3.7 (commit 2aa362c49), Linux kernel adds NT_FILE note to core
files which contains the files mapped by the process, including shared
libraries.
------------------------------------------------------------------------------
dwfl_core_file_report now tries to fall back on NT_FILE if the link_map chain
is broken.
elfutils would already find the appropriate binary file from
/usr/lib/debug/.build-id/ symbolic links. But those symbolic links do not have
to be present on the system while NT_FILE still points to the correct binaries.
Filenames from the note NT_FILE are used only if link_map filenames failed to
locate matching binaries.
tests/test-core.core.bz2 had to have its NT_FILE disabled as run-unstrip-n.sh
otherwise FAILs:
FAIL: 0x7f67f2aaf000+0x202000 - . - /home/jkratoch/redhat/elfutils-libregr/test-core-lib.so
PASS: 0x7f67f2aaf000+0x202000 - . - test-core-lib.so
As test-core-lib.so is found in link_map but it is not present on the disk
elfutils now chooses the more reliable filename from NT_FILE (although that
filename is also not found on the disk). Updating the expected text would be
also sufficient.

libdwfl: Add dwfl_getthread_frames.
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.

libdwfl: Introduce dwfl_module_getsym_info and dwfl_module_addrinfo.
Some arches like ppc64 use function descriptor values instead of function
addresses causing matching of names and addresses to fail when using
dwfl_module_getsym or dwfl_module_addrsym.
Add ebl hook to resolve any function descriptor values found in non-ET_REL
modules.
The new function dwfl_module_getsym_info doesn't adjust the symbol value
in any way, but returns the adjusted and/or resolved address associated
with the symbol separately. The new function dwfl_module_addrinfo resolves
against both the address associated with the symbol (which could be the
function entry address) value and the adjusted st_value. So that it is
easy to resolve and match either function descriptors and/or function
entry addresses.
Since these new functions also return more information they replace the
dwfl_module_getsym_elf and dwfl_module_addrsym_elf functions that never
made it into a released elfutils version.
addr2line and readelf now use the new functions when looking up functions
names. addr2line will now also display the section the address was found
in when given -x.
Extra testcases were added for both addr2line and the dwflsyms testscase.

Therefore elfutils now incorrectly matches on-disk file without build-id to an
in-core (in-memory) file with build-id.
In fact due to its known FIXME:
This verification gives false positive if in-core ELF had
build-id but on-disk ELF does not have any. But we cannot
reliably find ELF header and/or the ELF build id just from
the link map (and checking core segments is also not
reliable). */
So it probably should not be so ignorable as I did, one may want to analyze
build-id core files on CentOS-5, not sure. In fact it can be fixed, when we
find in dwfl_segment_report_module a module with build-id with conflicts in
its address range with existing non-build-id dwfl_link_map_report module we
should prefer the build-id module instead.
The problem is that once Dwfl_Module is added to Dwfl it cannot be easily
removed.
Originally elfutils called dwfl_segment_report_module first and then
dwfl_link_map_report.
Currently the order is dwfl_link_map_report and then
dwfl_segment_report_module only for modules missing from dwfl_link_map_report.
Patch below unfortunately needs bidirectional negotiation between the two
functions, therefore dwfl_link_map_report now no longer adds Dwfl_Modules to
Dwfl but it only stores information about them to r_debug_info_module.
This information is filtered then by dwfl_segment_report_module and only
filtered r_debug_info_module entries get finally added to Dwfl
(in dwfl_core_file_report).
NT_FILE would make all this magic easy but it is true that on CentOS-5 it
definitely does not exist.

libdwfl: Add minisymtab support.
Add an auxiliary symbol table dwfl_file aux_sym to Dwfl_Module if all we
have is the dynsym table. The main file might contain a .gnu_debugdata
section. The .gnu_debugdata section is a compressed embedded ELF file
that contains the text (code) section symbols from the symtab table
that are not in the main file dynsym table. dwfl_module_getsymtab (),
dwfl_module_addrsym () and dwfl_module_getsym () will use the auxiliary
symbol table when available (and no full symtab is available from the
debug file).
* libdwflP.h (struct Dwfl_Module): Add aux_sym, aux_symdata,
aux_syments, aux_symstrdata, aux_symxndxdata and aux_first_global.
(dwfl_adjusted_aux_sym_addr): New function.
(dwfl_deadjust_aux_sym_addr): Likewise.
(dwfl_adjusted_st_value): Take and check symfile argument.
(dwfl_deadjust_st_value): Likewise.
* dwfl_module_getdwarf.c (find_prelink_address_sync): Take and
use dwfl_file as argument to set address_sync.
(find_debuginfo): Call find_prelink_address_sync with debug file.
(find_aux_sym): New function.
(find_symtab): Use find_aux_sym if all we have is the dynsym table
and fill in aux DwflModule fields.
(dwfl_module_getsymtab): Return syments plus aux_syments.
(load_symtab): Always set first_global.
* dwfl_module_addrsym.c (dwfl_module_addrsym): Check symfile
when using same_section. Calculate first_global based on both
mod->first_global and mod->aux_first_global.
* dwfl_module.c (__libdwfl_module_free): Free aux_sym.
* dwfl_module_getsym.c (dwfl_module_getsym): Use auxsym table
to retrieve symbol and name if necessary, making sure all locals
from any table come before any globals.
* dwfl_module_info.c (dwfl_module_info): Call dwfl_adjusted_st_value
with symfile.
* relocate.c (resolve_symbol): Likewise.

Use index of first global symbol to speed up dwfl_module_addrsym search.
Cache the index of the first global symbol in the module's symbol table,
or -1 when unknown. All symbols with local binding come first in the
symbol table before the global symbols. Use this information to speed
up dwfl_module_addrsym search.
