Solving problems with the 0.10.0 migration

**READY TO MERGE**

I've search for all occurrences in the code of

CSUB_EXPIRATION
CSUB_THROTTLING
CASUB_EXPIRATION
REG_EXPIRATION

trying to fix all the cases in which int was used instead of long long. A second check of the reviewer is highly welcomed.

In addition, two utility scripts has been added to the repository. There are easy to use. To inspect types:

```
./type-analizer.py registrations expiration
./type-analizer.py csubs expiration
./type-analize.py casubs expiration
./type-analize.py csubs throttling
```
To change types to 64 bits:

```
./field-converster-64bits.py registrations expiration
./field-converster-64bits.py csubs expiration
./field-converster-64bits.py casubs expiration
./field-converster-64bits.py csubs throttling
```
