Werner Lemberg 602be7c810 [gzip] Improve building with external zlib (#49673).
Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
the following error.

  ftgzip.c
  zlib-1.2.8\zlib.h(86): error C2061:
                         syntax error: identifier 'z_const'
  zlib-1.2.8\zlib.h(94): error C2054:
                         expected '(' to follow 'z_const'
  zlib-1.2.8\zlib.h(94): error C2085:
                         'msg': not in formal parameter list
  ...
  zlib-1.2.8\zlib.h(877): fatal error C1003:
                          error count exceeds 100; stopping compilation

The error happens because FreeType keeps an own copy of zlib-1.1.4
under `src/gzip'.  When building `src/gzip/ftgzip.c' with
FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses

  #include <zlib.h>

which correctly finds an external `zlib.h', but `zlib.h' itself has
a line

  #include "zconf.h"

which makes Visual Studio 2015 find `src/gzip/zconf.h' while
compiling the files in `src/gzip'.

* src/gzip/zconf.h: Rename to...
* src/gzip/ftzconf.h: ... this.
* src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

  FreeType 2.7
  ============

  Homepage: http://www.freetype.org

  FreeType is a freely available software library to render fonts.

  It  is  written  in  C,  designed to  be  small,  efficient,  highly
  customizable, and  portable while capable of  producing high-quality
  output  (glyph  images) of  most  vector  and bitmap  font  formats.

  Please   read   the  docs/CHANGES   file,   it  contains   IMPORTANT
  INFORMATION.

  Read the  files `docs/INSTALL*'  for installation  instructions; see
  the file `docs/LICENSE.TXT' for the available licenses.

  The FreeType 2 API reference is located in `docs/reference'; use the
  file   `ft2-toc.html'   as   the   top  entry   point.    Additional
  documentation is available as a separate package from our sites.  Go
  to

    http://download.savannah.gnu.org/releases/freetype/

  and download one of the following files.

    freetype-doc-2.7.tar.bz2

  =============

  The preferred way  of communication with the FreeType  team is using
  e-mail lists.

    general use and discussion:      freetype@nongnu.org
    engine internals, porting, etc.: freetype-devel@nongnu.org
    announcements:                   freetype-announce@nongnu.org
    git repository tracker:          freetype-commit@nongnu.org

  Bugs
  ====

  Please submit bug reports at

    https://savannah.nongnu.org/bugs/?group=freetype

  Alternatively,    you   might    report    bugs    by   e-mail    to
  `freetype-devel@nongnu.org'.   Don't  forget   to  send  a  detailed
  explanation of the problem --  there is nothing worse than receiving
  a terse message that only says `it doesn't work'.


  Enjoy!
