  extension xmls: fix incorrect use of <ptype> tags
  
  I was having trouble using some GL/EGL loader generators because of some
  errors in the XML definitions for ANGLE.
  
  The first major problem is the content of the <ptype> tags. Let's refer
  to the Khronos registry XML schema (which is annoyingly a PDF rather
  than an xsd that we can test against, though I don't know if an xsd
  would catch this anyway):
  
      https://raw.githubusercontent.com/KhronosGroup/OpenGL-Registry/master/xml/readme.pdf
  
  In section 12.4.2, "Contents of <param> tags" it states:
  
      The <ptype> tag is optional, and contains text which is a valid type
      name found in <type> tag, and indicates that this type must be
      previously defined for the definition of the command to succeed.
      Builtin C types, and any derived types which are expected to be
      found in other header files, should not be wrapped in <ptype> tags
  
  Note that the above is repeated for the contents of <proto> tags as
  well.
  
  The extension XML files currently have a bunch of <ptype> tags which
  don't meet the expectations described above. The correct transformation
  for them would be, for example:
  
      <ptype>GLfloat *</ptype>      ->   <ptype>GLfloat</ptype> *
      <ptype>void *</ptype>         ->   void *
      <ptype>const char *</ptype>   ->   const char *
      <ptype>EGLAttrib *</ptype>    ->   <ptype>EGLAttrib</ptype> *
  
  The next issue is that some tags have some typos, such as "<pytpe>"
  instead of "<ptype>". (Now *that* is something an .xsd would catch...)
  
  The last issue is the use of the typename "GLvoid" which is not as
  serious a problem. It is still defined in Khronos' gl.xml <types> block,
  but Khronos no longer uses it in their XML registries. The comment for
  the "GLvoid" type in their <types> block states:
  
      <type comment="Not an actual GL type, though used in headers in the past">typedef void <name>GLvoid</name>;</type>
  
  So we might as well replace those with just plain "void".
  
  Anyway, long story short: to apply these transformations, I used Perl
  regular expressions, and applied these expressions in order:
  
  - Fix the tag misspellings:
  
      s#<(/?)pytpe>#<\1ptype>#g
  
  - Move the const qualifiers (if present) and pointer asterisk(s) (if
    any) outside the <ptype> tag itself:
  
      s#<ptype>(const )?([A-Za-z0-9]+)[ ]?(\*\*?)</ptype> #\1<ptype>\2</ptype> \3#g
  
  - Replace "GLvoid", "char", and "void" inside ptype tags to normal
    C types outside tags:
  
      s#<ptype>(GLvoid|void|char)</ptype>#\1#g
