Some job processing controls for proofing/copies

[michaelrsweet]

Proposed additions:

...
  PAPPL_JREASON_JOB_CANCELED_AFTER_TIMEOUT = 0x00800000, // 'job-canceled-after-timeout'
  PAPPL_JREASON_JOB_FETCHABLE = 0x01000000, // 'job-fetchable'
  PAPPL_JREASON_JOB_SUSPENDED_FOR_APPROVAL = 0x02000000 // 'job-suspended-for-approval'
...

// Return the job to the 'pending' or 'processing' state from 'processing-stopped', removing specified reasons as needed
extern void pappJobResume(pappl_job_t *job, pappl_jreason_t remove) _PAPPL_PUBLIC;

// Stop/suspend a 'processing' job to the 'processing-stopped' state, adding specified reasons as needed
extern void pappJobSuspend(pappl_job_t *job, pappl_jreason_t add) _PAPPL_PUBLIC;

These will go along with the changes for #265 to support proof print copies, INFRA, and the "job-cancel-after-xxx" Job Template attributes.

Thanks - I'll copy / paste this into my own branch to move forward.

Renaming functions to papplJobResume and papplJobSuspend.

[wifiprintguy]

papplJobResume() is already defined with a different parameter signature, unless I've gotten my fetches and rebases all messed up (again)...

[michaelrsweet]

@wifiprintguy That's certainly possible, current master has these in job.h:

extern void		pappJobResume(pappl_job_t *job, pappl_jreason_t remove) _PAPPL_PUBLIC;
extern void		pappJobSuspend(pappl_job_t *job, pappl_jreason_t add) _PAPPL_PUBLIC;
