Great renaming: use "series" instead of "family".
This is for greater consistency with the ST application notes, which refer to migrating "across" series (e.g. F1 to F2), but compatibility "within" a family (e.g. F1). So: - Move libmaple/stm32x/include/family to .../include/series/ and fix up includes appropriately. - Refer to "family" headers as "series" headers in comments. - Make similar "find and replace"-style changes to build system variable names and comments. - Move support/ld/stm32/family to .../stm32/series.
