Siegfried Pammer d8dfbec04b Write XAML a XAML parser can read back

Two of the defects reported on issue #2253 come from the decompiler
writing text that means something else when it is read again.

A markup extension is written as a single attribute value, and its
grammar gives ',' '=' '{' '}' and the quote characters a meaning. Values
went out unquoted, so an argument carrying any of them was read back as
further name/value pairs: {DXBinding Expr='Price - Prev > 0 ? ...'}, the
reported case, no longer compiles at all (MC3042, MC3045). Values without
such a character stay unquoted, because quoting them would rewrite every
document that never needed it.

A clr-namespace declaration names the CLR namespace it maps, but nothing
read that name out of it, so no lookup by namespace could match a
declaration the document itself had made. Every type in such a namespace
then got a second prefix declared on the element that used it. The
assembly is the second half of the same lookup, and there the document
records the name it was written against while a well-known type carries
the assembly it resolves to now - "mscorlib" against
"System.Private.CoreLib" - so the two are also accepted as the same when
the recorded assembly forwards the type.
