Mid(foo, 1) is equivalent to [foo], if all you want is the character. Similarly
Left(1) is [0]. It is faster also, since it does not need to create intermediate
strings.
Right(1) is a touch more tricky, since it requires something like GetLength() ?
[GetLength() - 1] : 0;. A new method, Last() has been added to perform this
character extraction.
Multiple call sites have been updated to use more efficient/simpler
syntax. There are a number of call sites that use on these patterns, but based
on the surrounding context we actually need/want a string, so they have not been
modified.

This method duplicates the behaviour of the const [] operator and
doesn't offer any additional safety. Folding them into one
implementation.
SetAt is retained, since implementing the non-const [] operator to
replace SetAt has potential performance concerns. Specifically many
non-obvious cases of reading an element using [] will cause a realloc
& copy.

The various string/byte classes support Mid(), Left(), and Right() for
extracting substrings. Mid() can handle all possible cases, but Left()
and Right() are useful for common cases and more explicit about what
is going on.
Calls like Mid(offset, length - offset) can be converted to
Right(length - offset). Calls like Mid(0, length) can be converted to
Left(length).
If the substring being extracted does not extend all the way to one of
the edges of the string, then Mid() still needs to be used.

It just returns false. Also make more CBC_HighLevelEncoder members
const.

Nothing in fxbarcode/ depends on XFA code. This CL moves xfa/fxbarcode
to be fxbarcode/ and creates a static_library for fxbarcode which is
depend on by the xfa library.
