John E. Malmberg 25f351424b VMS: fix and generate the VMS build config
config_h.com is a new file that generates a config.h file based on the
curl_config.h.in file and a quick scan of the configure script.  This is
actually a generic procedure that is shared with other VMS packages.

The existing pre-built config-vms.h had over 100 entries that were not
correct and in some cases conflicted with the build options available in
the build_vms.com.

generate_config_vms_h_curl.com is a helper procedure to the
config_h.com.  It covers the cases that the generic config_h.com is not
able to figure out, and accepts input from the build_vms.com procedure.

build_curlbuild_h.com is a new file to generate the curlbuild.h file
that Curl is now using when it is using a curl_config.h file.

post-config-vms.h is a new file that is needed to provide VMS specific
definitions, and most of them need to be set before the system header
files are included.

The VMS build procedure is fixed:

   1. Fixed to link in the correct HP ssl library.
   2. Fixed to detect if HP Kerberos is installed.
   3. Fixed to detect if HP LDAP is installed.
   4. Fixed to detect if gnv$libzshr is installed.
   5. Simplified the input parameter parsing to not use a loop.
   6. Warn that 64 bit pointer option support is not complete
      in comments.
   7. Default to IEEE floating if platform supports it so
      resulting libcurl will be compatible with other
      open source projects on VMS.
   8. Default to LARGEFILE if platform supports it.
   9. Default to enable SSL, LDAP, Kerberos, libz
      if the libraries are present.
   10. Build with exact case global symbols for libcurl.
   11. Generate linker option file needed.
   12. Compiler list option only commonly needed items.
   13. fulllist option for those who really want it.
   14. Create debug symbol file on Alpha, IA64.

How to Build:

The (brute-force) builder is [.packages.vms]build_vms.com.  Comments in
this procedure describe various optional parameters which enable or
disable optional program features, or which control the build in other
ways.  Product files (.EXE, .H, .LIS, .MAP, .OBJ, .OLB, ...) should be
produced in an architecture-specific subdirectory under this directory
([.ALPHA], [.IA64], [.VAX]).

   Example build commands:

      @ [.packages.vms]build_vms.com CLEAN
      @ [.packages.vms]build_vms.com LARGE LDAP
      submit /noprint [.packages.vms]build_vms.com /param = (LARGE, LDAP)


Other Notes:

The test suites are not supported as of 7.11.0.

The curlmsg.sdl and curlmsg.h files are generated from curlmsg.msg.
This is not done automatically, since the .MSG file is a hand edit
of the relevant stuff from the curl.h file.  If you want to do this
yourself you'll need the SDL package from the freeware collection.
