Security fix in "zlib":

- upgrade zlib to 1.2.2
  (originally:  2005/03/23 21:08:13+01:00 serg@serg.mylan )
- fixed linking with zlib
  (originally:  2005/05/24 22:42:43+02:00 lenz@mysql.com )
- one more build fix for zlib.lib - added libpath to the mysql_test_run_new project files
  (originally:  2005/05/25 10:55:21+02:00 lenz@mysql.com )
- Do not build the RPMs statically on i386 by default, only when adding either
  "--with static" or "--define '_with_static 1'" to the RPM build options.
  Static linking really only makes sense when linking against the specially patched
  glibc 2.2.5.
  (originally:  2005/06/14 21:39:08+02:00 lenz@mysql.com )
- Apply security patch to bundled zlib for CAN-2005-2096. (Bug #11844)
  (originally:  2005/07/11 10:37:21-07:00 jimw@mysql.com )
- applied a security fix to inftrees.h from the bundled zlib to resolve a second
  potential zlib security vulnerability (CAN-2005-1849). Fix was taken from the
  official zlib-1.2.3 distribution (no other zlib-1.2.3 changes were applied)
  (originally:  2005/07/27 14:55:08+02:00 lenz@mysql.com )
- build the RPM binaries against the bundled zlib, when static linking is requested
  (originally:  2005/07/27 16:42:13+02:00 lenz@mysql.com )

  clarify help text
support-files/mysql.spec.sh:
  - Do not build statically on i386 by default, only when adding either "--with
    static" or "--define '_with_static 1'" to the RPM build options. Static
    linking really only makes sense when linking against the specially patched
    glibc 2.2.5.
  - build against the bundled zlib, when linking statically

linking really only makes sense when linking against the specially patched

17. Why am I getting this "register_frame_info not found" error on Solaris?
After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
generates an error such as:
ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
symbol __register_frame_info: referenced symbol not found
The symbol __register_frame_info is not part of zlib, it is generated by
the C compiler (cc or gcc). You must recompile applications using zlib
which have this problem. This problem is specific to Solaris. See
http://www.sunfreeware.com for Solaris versions of zlib and applications
using zlib.

The compressed data format used by the in-memory functions is the zlib
format, which is a zlib wrapper documented in RFC 1950, wrapped around a
deflate stream, which is itself documented in RFC 1951.
The compressed data format used by default by the in-memory functions is
the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
around a deflate stream, which is itself documented in RFC 1951.
The library also supports reading and writing files in gzip (.gz) format
with an interface similar to that of stdio using the functions that start
with "gz". The gzip format is different from the zlib format. gzip is a
gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
This library can optionally read and write gzip streams in memory as well.
The zlib format was designed to be compact and fast for use in memory
and on communications channels. The gzip format was designed for single-
file compression on file systems, has a larger header than zlib to maintain
directory information, and uses a different, slower check method than zlib.
This library does not provide any functions to write gzip files in memory.
However such functions could be easily written using zlib's deflate function,
the documentation in the gzip RFC, and the examples in gzio.c.
The library does not install any signal handler. The decoder checks
the consistency of the compressed data, so the library should never
crash even in case of corrupted input.
