a4dd89f214 Improve code-generation for Strings 
Make String::Data use trivial copy of the short/long union to avoid
unnecessary branching there, inline release() as it can be elided by
the compiler on moved-from Strings.

56611604b2 Make String able to reference external data without copying 
Sometimes we really need to have a String instead of a StringView,
but some of those strings might not need to own their data. Make
it possible to explicitely construct a String that does not own
the underlying buffer.

Use it when parsing balanced strings.

f41d78083a Use the extra_word_chars option in word based normal commands 
the completion_extra_word_chars is now gone, superseeded by
extra_word_chars that gets used both for completion and for normal mode.

1ccccbce04 Fix horrible leak in String::Data::operator=(String::Data&&) 
And that, my friends, is why we recommend using standard containers
instead of rolling your own.

more appropriate, take column size of codepoints into account for
vertical movements and docstring wrapping.

e701254b02 Fix String::Data::reserve on big endian platforms, and document String::Data 
reserve was not ensuring the capacity would be pair, which is needed
on big endian machines, as we use its least significant bit to flag
short string optimizations. On little endian the bit we use is the
8th most significant (the least significant bit of the last byte),
so we were not hitting any problems.
