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.

Use seek+read instead of pread to read from /dev/$$/mem files.
pread[64] always returns EINVAL when negative offsets are used.
read+seek allows us to read in-memory vdso objects mapped high in the
address space.

libdwfl: dwfl_linux_proc_find_elf use elf_from_remote_memory for (deleted).
If a module has a "(deleted)" main ELF file, then try to read it from
remote memory if the Dwfl has process state attached by reusing the ptrace
mechanism from linux-pid-attach.

libdwfl: elf_from_remote_memory should use pagesize, not p_align.
elf_from_remote_memory would use the actual p_align of the PT_LOAD segments
to calculate the loadbase, end and start of a segment. But the dynamic
loader aligns the segments using the pagesize and only sanity checks the
p_align values. So we should do the same to get accurate segment addresses.
Also fixes a small memory leak in case the ELF image appears to be bad.

libdwfl: linux-proc-maps.c (proc_maps_report): Don't assert on bad input.
If ino == last_ino && dmajor == last_dmajor && dminor == last_dminor then
we expect the file names to be the same as well. Which is reasonable if
the input came from the /proc file system. But there could be bad user
input if the file was supplied through dwfl_linux_proc_maps_report.
Instead of asserting on the bad input, just signal a bad_report.

libdwfl: Add dwfl_core_file_attach and dwfl_linux_proc_attach.
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.

libdwfl: dwfl_linux_proc_find_elf should only return regular files.
When the dwfl_linux_proc_find_elf callback is used together with the
dwfl_linux_proc_report callback that reads /proc/PID/maps files we might
see and try to open special character device files that cannot be normally
read and processed by libelf (and might hang the library on the initial
open or read from the file). Make sure we only try to open and return
regular files.

libdwfl: Don't report and abort on non-file mappings in maps.
proc_maps_report, used for -p or -M, could report modules with names
that were not absolute file names (and not the special vdso marker).
dwfl_linux_proc_find_elf would abort on such names. This isn't a very
nice thing to do in a library. Make sure only real (absolute) file
mappings are reported and don't abort when unexpected file names are
found, just report failure.
Test case with some examples as found in Linux /proc/PID/maps added.

libdwfl: proc_maps_report should not fclose the given file.
Calling fclose only on bad_report, but not on other errors or success
is confusing. The caller is always responsible for calling fclose on
the given file. Otherwise flcose might be called twice (e.g. in
dwfl_linux_proc_report).
