Added test for codecs.
Fix issue with Bach polling.

Bach would only read as much data as fitted into one buffer page,
aborting the read too early.
Added test for encoding brackets.

Which unfortunately fail with the XML codec.
Properly escape html strings.

All html strings containing <>&'" should always be escaped, to allow for
these characters to be expressed in attributes and text nodes.
This incurs a slight overhead, as we now need to allocate new strings as
well as iterate over existing ones. This cannot be avoided though.
Added tests for escaping characters in codecs.

Bach doesn't correctly escape though, so I disabled that for now.
Properly implement test.

Bach isn't correctly escaping characters, so that's disabled for now.
However, "packed" and "xml" are important to test, since these are most
used.
"packed" is used for all network traffic, and "xml" is used for
persistence on the server and client. "bach" however isn't actually used
currently as far as I know.
Bump version.
Correctly check headers.
Harmonize autogen.sh within project.

This version should work on all supported platforms, opting to using
autoreconf if available.
Use a more proper name.
