Add the feature "dmpstore -l" and "dmpstore -s".

Browse Source 
The file format is as below:
<File> := <Variable>+
<Variable> := <Name-Size> <Data-Size> <Name> <GUID> <Attributes> <Data> <Crc32>

Each variable representation in the file has a CRC32 value which can provide a mechanism to detect the file modification.
When any CRC32 is incorrect, dmpstore rejects to load the variables from the file.
