The i2c core in the golden SVEC firmware is the OpenCores i2c
master, and differs from the one used in the fine delay and
the SPEC. So we grab this code from Tom to read the EEPROM
(originally at /user/twlostow/svec/software/sveclib/golden_i2c.c,
and probably adapted from the opencores sources).

polling removed, now it sleeps between retries.

Because vmebase1 does not exist anymore...

Rubini's 'check-fmc-bus' script added.
vmebridge local includes removed.

Move BASE_LOADER definition to svec.h, adding a SVEC_ prefix before.
Update default fw name to svec_golden.bin
Cut some lines to 80 chars.

- Erased trailing whitespaces
- 80 char line length
