- the macros are gone
- there's no more code in this file,
LGPL + GPL = GPL,
and the code that was moved to lib/bcd.c is anyway trivial

This updates <linux/bcd.h> to define the key routines as constant
functions, which the macros will then call. Newer code can now call
bcd2bin() instead of SCREAMING BCD2BIN() TO THE FOUR WINDS.
This lets each driver shrink their codespace by using N function calls to
a single (global) copy of those routines, instead of N inlined copies of
these functions per driver.
These routines aren't used in speed-critical code. Almost all callers are
in the RTC framework. Typical per-driver savings is near 300 bytes.

Cleanup patch from Hollis Blanchard <hollis@austin.ibm.com>
We have a large number of private implementations of BIN_TO_BCD and
BCD_TO_BIN, which are all the same. And a lot of them are inflexible because
they modify their arg:
#define BIN_TO_BCD(val) ((val)=(((val)/10)<<4) + (val)%10)
- Create (in <linux/bcd.h> a generic BIN2BCD/BCD2BIN which does not modify
its arg
- Create generic BIN_TO_BCD/BCD_TO_BIN which uses the above
- Update lots of callers to use the new generic version.
