5320a4aa38 memory: Implement xmlGrowCapacity to safely grow arrays 
xmlGrowCapacity makes sure that dynamic arrays don't grow beyond an
explicit maximum size. size_t considerations are also taken into account.
A macro XML_MAX_ITEMS is provided as default maximum with value
1 billion.

When fuzzing, the initial size is set to 1 to cause more reallocations.
This can require adjustments if callers really need larger arrays.

e014cc570f xpath: Remove non-standard xf:escape-uri function

unlikely to be used these days.

bf5fcf6e64 xpath: Use separate static hash table for standard functions 
This avoids registering standard functions when creating an XPath
context.

Lookup of extension functions is a bit slower now, but ultimately, all
function lookups should be moved to the compilation phase.

5c9abbf831 SAX2: Fix xmlSAX2ResolveEntity if systemId is NULL 
Passing a NULL systemId results in snprintf("%s", NULL) which crashes on
some platforms. Regressed with commit 4ff2dccf.

Note that systemId should never be NULL during normal parsing. It can
only be NULL if API functions are called with a NULL systemId.

Should fix #825.

When building on Windows, we must link against `Bcrypt` to satisfy the
use of `BCryptGenRandom`. Add this to the link interface in CMake to
allow use of libxml2 as a static library.
