* priv.h (PM_WRITEWAIT): New pagemap bit.
* data-return.c (_pager_do_write_request): Don't proceed with a
pageout if one is already in progress. Once we finish, wake up
any potential PM_WRITEWAIT waiters.
* priv.h (PM_INIT): Provide value again.
* data-return.c (_pager_do_write_request): Track PM_INIT again.
* priv.h (struct pager): Make pagemap consist of 16-bit elements
instead of only 8 bits.
* data-request.c (_pager_seqnos_memory_object_data_request):
Make PM_ENTRY a short pointer.
* data-return.c (_pager_do_write_request): Make PM_ENTRIES a short
pointer.
* lock-object.c (_pager_lock_object): Make PM_ENTRIES a short
pointer.
* mark-error.c (_pager_mark_next_request_error): Make P a short
pointer.
(_pager_mark_object_error): Likewise.
* offer-page.c (pager_offer_page): Make PM_ENTRY a short pointer.
* object-terminate.c (_pager_free_structure): Interpret
pagemapsize correctly.
* pagemap.c (_pager_pagemap_resize): Likewise.
