Options: Code reorganization and faster option lookup

* Speedup option lookup by using a auxiliary hash table.
* Move many routines around to make the implementation easier to follow.
Eventually, we may split options.c in two, all of the query routines
PetscOptionsGetXXX() do not need (and should not have) access to the
PetscOptions data structure.
* Restore proper handling of monitors in set/clear option events.
* Add PetscOptionsHasHelp(), eventually we may add a "category" argument
to do special handling of let say `-help <package>`
* Change PetscOptionsReject() to handle option prefix, this makes the call
easier to use in XXXSetFromOptions() implementations.

PCFieldSplit: Interface to set -pc_fieldsplit_detect_saddle_point programmatically

Adds a new boolean data field for this setting, and a setter and getter.

Removes a call to get the option outside of PCSetFromOptions_FieldSplit.

In PCSetFromOptions_Fieldsplit(), checks the flag and then immediately
calls PCFieldSplitSetDetectSaddlePoint(), which then set the split type
and SchurPre type, as before.

Wraps setting PC_FIELDSPLIT_SCHUR_PRE with the existing API.

Updates documentation, in particular removing a statement that negative diagonal
entries trigger a split (when only zero diagonal entries do).

Merge branch 'psanan/manpages-notes-newlines' [PR #932]

* psanan/manpages-notes-newlines:
A large number of man pages are improperly formatted because of the lack of a newline after "Notes:", "Fortran Notes:", or "Developer Notes:".
This batch adds those newlines, with 4 spaces of indentation afterwards.
The uniform indentation arguably makes the man pages a little less readable in the source itself,
but overall this hopefully has a large positive impact on the readability of the HTML pages.
