The actual condition for the optimization is invariance from context list
-- this includes both position() and last().
Instead of splitting the posinv concept just include last() into
non-posinv expressions - this requires sorting for boolean predicates that
depend on last() and do not depend on position(). These cases should be
very rare.

translate() with constant arguments now uses a 128-byte table and a table
lookup instead of searching characters in the source string. The table is
generated during query optimization.

When allocating new pages, make sure that the page has at least 1/4 of the
base page size free. This makes sure that we can do small allocations after
big allocations (i.e. huge node lists) without doing a heap alloc.
This is important because XPath stack code always reclaims extra pages after
evaluating sub-expressions, so allocating a small chunk of memory and then
rolling the state back is a common case (filtering a node list using a
predicate usually does this).
A better solution involves smarter allocation rollback strategy, but the
implemented solution is simple and practical.

Temp folder is the root folder on Windows; writing to the folder may require administrator rights.
We can't use current folder for temporaries because tests from different configurations can be running
in parallel, but executable folder is always safe since we only run each executable once.

Introduce a notable behavior change in default parsing mode: documents without a
document element node are now considered invalid. This is technically a breaking change,
however the amount of documents it affects is very small, all parsed data still persists,
and lack of this check results in very confusing behavior in a number of cases.
In order to be able to parse documents without an element node, a fragment parsing flag is
introduced.
Parsing a buffer in fragment mode treats the buffer as a fragment of a valid XML.
As a consequence, top-level PCDATA is added to the tree; additionally, there are no
restrictions on the number of nodes -- so documents without a document element are considered
valid.
Due to the way parsing works internally, load_buffer_inplace occasionally can not preserve
the document contents if it's parsed in a fragment mode. While unfortunate, this problem is
fundamental; since the use case is relatively obscure, hopefully documenting this shortcoming
will be enough.

Parsing used to work on a non null-terminated buffer, inserting a fake null terminator to increase performance.
This makes it impossible to implement fragment parsing that preserves PCDATA contents (as witnessed by some
tests for boundary conditions that actually depended on this behavior).
Since almost all uses result in us allocating an internal buffer anyway, the new policy is to make sure all buffers
that are allocated by pugixml are null-terminated - the only exception now is external calls to load_buffer_inplace
that don't trigger encoding conversion.

In case a test sets memory-management functions to perform custom testing and fails midway,
all subsequent tests that rely on custom memory handling (i.e. threshold) can fail unexpectedly.
Setting up the functions before every test fixes this, making all tests self-contained.

This expands and replaces the Travis-specific makefile by adding more options and correctly tracking header dependencies.
Also add wchar_t mode test to Travis configuration.
