Several things irk me about passing values as const pointers:
* They can be NULL, which is not a valid value.
* They require explicit temporary variables for storage.
* They don't compose easily in a legible manner, requiring
weird pointer passing semantics where the variable being assigned
is hidden as an argument in the innermost function call.
* We can't change the value through the pointer, requiring yet more
local variables to hold copies of the input value.
In the device interface where we pass a matrix to a function, we often
find ourselves making a local copy of the matrix so we can concatenate
other transforms to it. This copying is a lot of unnecessary busywork
that I hope to eventually avoid by laying the groundwork with this
commit.
This is a rather large API change, so I apologize for the inconvenience,
but I hope the end result and gain in legibility will be worth the pain.

Currently, our API uses static inlines for fz_lock and
fz_unlock, the definitions for which depend on whether
we build NDEBUG or not. This isn't ideal as it causes
problems when people link a release binary with a debug
lib (or vice versa).
We really want to continue to use static inlines for the
locking functions as used from MuPDF, as we hit them
hard in the keep/drop functions.
We therefore remove fz_lock/fz_unlock from the public API
entirely. Accordingly, we move the fz_lock/fz_unlock
static inlines into fitz-imp.h (an internal header),
together with the fz_keep_.../fz_drop_... functions.
We then have public fz_lock/fz_unlock functions for any
external callers to use that are free of compilications.
At the same time, to avoid another indirection, we change
from holding the locking functions as a pointer to a
struct to a struct itself.

All link destinations should be URIs, and a document specific function
can be called to resolve them to actual page numbers.
Outlines have cached page numbers as well as string URIs.

Make fz_link reference counting threadsafe.
Remember to free dests of GOTO links. Accordingly, ensure that XPS
does not create links with uninitialised dests.
