41c10c0cec io: Don't cast file descriptors to pointers 
This doesn't work if open() returns 0 which is rare but can happen. Wrap
the fd in a context struct.

Fixes #835.

ab62fc27e8 gitlab-ci: Add --with-valid to medium config

2e18e5dc6d memory: Grow dynamic arrays by 50% 
Growing by a factor lower than the golden ratio increases the chances of
reusing memory freed from earlier allocations. Set growth rate to 1.5
which also reduces internal fragmentation.

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.

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.
