BMC Minimum ship Level

This code compares the BMC_MSL defined at compile time,
It will parse the new fw (explicit at MANIFEST file) and use regex to
evaluate it  and compare BMC_MSL against version from MANIFEST.
If newer or equal  it will apply, otherwise it will fail,
preventing activation  operation.

Tested:
 regex-bmc-msl="([a-z]+[0-9]{2})+([0-9]+).([0-9]+).([0-9]+)"
 fw-package="version=fw1010.00-28.4-0-ge611abca21"
 bmc-msl="fw1010.00-27"  proceeds with activation...
 bmc-msl="fw1010.00-29"  returns:
