Remove faulty fclose() call.  Thanks to Andrea Morandi and Sean Young.

Adjusted the search function to find the symbol associated with an
address when EIP address resolving is enabled.

We need to read all symbols

Improved symbol lookup, since symbols are spread over the entire
address space.  Return the symbol that fits best instead of the first hit.

Only read kernel symbols from /proc/kallsyms if no System.map has been read

Return of the symbols.

Linux 2.6 exports its symbols in /proc/kallsyms and does not implement
query_module() anymore.  Thus, the entire scanner has been overhauled.

Log message

Improved query_module calls and unified code against former version (1.12)

Added missing defines and a prototype so that the code compiles.
Removed old code that is neither supported nor working anymore

Conversion to file coding style

Patch by Kelledin to use the newer query_module function rather than
the old obsolete hack of stepping thru /dev/kmem.

Added a private module.h with extracted data from Linux 2.2 to replace
<linux/module.h> which creates a number parse errors.

There's a problem with including kernel-space header files on the
little endian MIPS architecture.  According to Ryan Murray this should
help and also work on all architectures.

 . Use lseek64() instead of llseek() which is deprecated these days
 . Keith Owens <kaos@ocs.com.au>
   - Fixed bug that caused klogd to die if there is no sym_array available.
   - When symbols are expanded, print the line twice.  Once with
     addresses converted to symbols, once with the raw text.  Allows
     external programs such as ksymoops do their own processing on the
     original data.

  * ``-m 0'' turns off -- MARK -- now. (closes: Bug#28629, Bug#31494)
  * Changed Greg's e-mail address to represent his current one.
  * Shortened line length for kernel logging slightly.
  * Corrected return value of AddModule (closes: Bug#30093)
  * Finally fixed an error with `-a' processing, thanks to Topi Miettinen
    <tom@medialab.sonera.net> (closes: Bug#30462)

Added additional array boundary check.

Corrected Mark's email address.

  * Fixed typos in syslogd-listfiles(1), thanks to Francesco Potorti`
    <F.Potorti@cnuce.cnr.it> (closes: Bug#20903)
  * Corrected email address for Shane Alderton (closes: Bug#20765)
  * Fixed manpage to not reflect reverse implementated SIGALRM signal
    handler (closes: Bug#20647)
  * Modified behaviour with including <sys/module.h> (closes: Bug#20556)
  * Added correct prototype for llseek() (closes: Bug#20507, Bug#20220)
  * Added more log information if problems occurr while reading a system
    map file.
  * Modified System.map read function to try all possible map files until
    a file with matching version is found.
  * Added Debian release to klogd
  * Switched to fgets() as gets() is not buffer overrun secure.
  * Modified loop for detecting the correct system map.

  * Applied patch from Pedro Manuel Rodrigues <pmanuel@cindy.fe.up.pt> to
    let klogd work togther with >2GB address space.

  * Another patch for Linux/alpha by Christopher C Chimelis
    <chris@classnet.med.miami.edu> (fixes: Bug#17385)

  * Corrected some code that caused klogd to dump core when receiving some
    special messages from 2.1.78.  Thanks to Chu-yeon Park
    <kokids@doit.ajou.ac.kr> for informing me.
  * Fixed bug that caused klogd to die if there is no System.map
    available.
  * Added -x switch to omit EIP translation and System.map evaluation.
    Thanks to Florian La Roche <florian@knorke.saar.de>.
  * Fixed small bugs in F_FORW_UNKN meachanism.  Thanks to Torsten Neumann
    <torsten@londo.rhein-main.de> for pointing me to it.
  * Fixed problem with klogd not being able to be built on a kernel newer
    than 2.1.18.  Worked in a patch from Alessandro Suardi <asuardi@uninetcom.it>

Some more glibc patches made by Michael Alan Dorman <mdorman@debian.org>.

Added patch from Leland Olds which fixes a buffer overrun and improved
symbol lookup.
