Vadim Zeitlin 344cc940a0 Impose upper limit on memory allocation in wxString::PrintfV() ...

Don't loop indefinitely until we run out of memory, possibly after
wrapping around INT_MAX, but impose an arbitrary limit of 128MiB for the
max allocation done by wxString::PrintfV() when the provided format
string or one of the arguments are invalid.

This notably fixes a crash when trying to use "%c" to output an invalid
Unicode character.

Also improve comment explaining DoStringPrintfV() logic and change the
size type to size_t from int.
