This CL rebuilds the text edit engine in a simpler fashion. Instead of
depending on multiple pages, paragraphs and buffer fields there is a
single text edit engine which contains a gap buffer.
This makes the code easier to understand and follow.

Through out the code base there are numerous places where variables
are declared using a signed integer type when interacting with the
string classes, since they assume that FX_STRSIZE is 'int'. As part of
changing the underling type of FX_STRSIZE to be unsigned, these
locations are being changed to use FX_STRSIZE. This is necessary as
part of converting the type, but has been broken off into a separate CL,
since it should be low risk.
Some related cleanups that are low risk are included as part of
this CL.

This CL cleans up the GetPre* methods in CFDE_TextEdtEngine. In
particular:
* GetPreDeleteText was inlined as it was very simple
* GetPreReplaceText was removed as unused
* GetPreInsertText was renamed to InsertIntoTextCopy to make clear
that this was doing the insert into a copy of the text.

Previously text break was a unique_ptr inside the CFDE_TxtEdtEngine.
This CL converts it to be a member instead of a unique_ptr. We never
replace the pointer after it's created.
