8655  * 'read_job_ticket()' - Read a job ticket embedded in a print file.
8656  *
8657  * This function only gets called when printing a single PDF or PostScript
8658  * file using the Print-Job operation.  It doesn't work for Create-Job +
8659  * Send-File, since the job attributes need to be set at job creation
8660  * time for banners to work.  The embedded job ticket stuff is here
8661  * primarily to allow the Windows printer driver for CUPS to pass in JCL
8662  * options and IPP attributes which otherwise would be lost.
8663  *
8664  * The format of a job ticket is simple:
8665  *
8666  *     %cupsJobTicket: attr1=value1 attr2=value2 ... attrN=valueN
8667  *
8668  *     %cupsJobTicket: attr1=value1
8669  *     %cupsJobTicket: attr2=value2
8670  *     ...
8671  *     %cupsJobTicket: attrN=valueN
8672  *
8673  * Job ticket lines must appear immediately after the first line that
8674  * specifies PostScript (%!PS-Adobe-3.0) or PDF (%PDF) format, and CUPS
8675  * stops looking for job ticket info when it finds a line that does not begin
8676  * with "%cupsJobTicket:".
8677  *
8678  * The maximum length of a job ticket line, including the prefix, is
8679  * 255 characters to conform with the Adobe DSC.
8680  *
8681  * Read-only attributes are rejected with a notice to the error log in
8682  * case a malicious user tries anything.  Since the job ticket is read
8683  * prior to attribute validation in print_job(), job ticket attributes
8684  * will go through the same validation as IPP attributes...
