Previously the error offset pointed to the first mismatching character, which
can be confusing especially if the start tag name is a prefix of the end tag
name. Instead, move the offset to the first character of the name - that way
it should be more obvious that the problem is that the entire name mismatches.
Fixes#112.
When using format_raw the space in the empty tag (<node />) is the only
character that does not have to be there; so format_raw almost results in
a minimal XML but not quite.
It's pretty unlikely that this is crucial for any users - the formatting
change should be benign, and it's better to improve format_raw than to add
yet another flag.
Fixes#87.
Previously there was no guarantee that the tests that check for out of memory
handling behavior are actually correct - e.g. that they correctly simulate out
of memory conditions.
Now every simulated out of memory condition has to be "guarded" using
CHECK_ALLOC_FAIL. It makes sure that every piece of code that is supposed to
cause out-of-memory does so, and that no other code runs out of memory
unnoticed.
This should completely eliminate the confusion between load and load_file.
Of course, for compatibility reasons we have to preserve the old variant -
it will be deprecated in a future version and subsequently removed.
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.
