Add an MCU_SERIES variable to each of the files under
support/make/board-includes, which declares the series as "stm32f1" in
each case.
Use this in target-config.mk when determining LD_SERIES_PATH (with a
hack since we only support performance line) and
LIBMAPLE_MODULE_SERIES. We must move support/ld/stm32/series/f1 to
.../series/stm32f1 as a side-effect.
Adding support for other series (e.g. "stm32f2") should now be a
matter of filling in the contents of libmaple/<series>/ and
support/ld/stm32/<series>/ appropriately (along with moving the rest
of the nonportable code out of the libmaple core and into the STM32F1
series submodule).

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.

Move
support/ld/stm32/f1/performance/vector_symbols.inc
to
support/ld/stm32/family/f1/performance/vector_symbols.inc
Creating directory "family" under support/ld/stm32 will allow parallel
directories (e.g. support/ld/stm32/mcu) to exist, which allows an
eventual linker script cleanup to go much more smoothly.

We're no longer even marginally compatible with CS3, so it's
inappropriate to use that prefix in our names.
Rename:
__cs3_stm32_vector_table -> __stm32_vector_table.
__cs3_stack -> __msp_init
__cs3_reset -> __exc_reset
__cs3_start_c -> start_c
Also add an MIT license header and assert LeafLabs copyright over
wirish/start.S and wirish/start_c.c. These files are modified from
the original CodeSourcery versions, which were distributed under a
license that permits modifications to be distributed under a different
copyright and licensing terms than the originals.

- support/make/target-config.mk: add LD_FAMILY_PATH, the directory to
search for STM32 family-specific link configuration files. For now,
this is just a stub which points to support/ld/stm32/f1/performance,
since that's all we currently support. We can add the logic to
support different STM32 families here later.
- Makefile: Pass -L $(LD_FAMILY_PATH) to linker.
- Rename support/ld/names.inc to
support/ld/stm32/f1/performance/vector_symbols.inc.
- common.inc: INCLUDE vector_symbols.inc instead of names.inc.
