Synopsis: Correctly read mime type in httpfsys when charset
           is appended to the string (as in JSP 2.0 servers)

Overview: A customer was using a Java Server Page server to generate
           SMIL presentations. After the customer upgraded their
           JSP server to 2.0, they found that the generated SMIL
           presentations would no longer work in our player (any
           version), but rather would attempt an AU.

           What was happening was that the JSP 2.0 spec specifies
           that under certain conditions, the charset should be
           appended to the "Content-Type" header, as in:

           Content-Type: application/smil;charset=ISO-8859-1

           For more information, see the JSP 2.0 spec at:

           http://www.jcp.org/aboutJava/communityprocess/review/jsr152

           httpfys was taking the whole string as the mime type,
           and therefore could not match mime types with any
           available file format. Also, since the URL had a
           .jsp extension, then it couldn't match on file
           extension either. So we AU'd.

           The fix is simply to search for a ';' in the
           "Content-Type" string and ignore it and anything that
           comes after it.

Files Modified:
filesystem/http/httpfsys.cpp

Image Size and Heap Use impact: tiny increase

Platforms and Profiles Affected: all that use full httpfsys

Distribution Libraries affected: none

Distribution library impact and planned action: n/a

Platforms and Profiles Build Verified: win32

Platforms and Profiles Functionality verified: win32

Branch: head, 116Nep, 130NepX, others?

QA Instructions:

This URL should work both before and after the fix:

http://sander.internet.eo.nl:8080/real/index.jsp

This URL should only work after the fix:

http://sander.internet.eo.nl:9090/real/index.jsp
