parser can't generate 64 bit integer types

[devendranaga]

For ex: when in uper mode, a value of 43980465111903 gives out -1 when compiled and linked in 32 bit mode (gcc -m32) or on an embedded box.

the problem is with the asn_per_constraints_t structure being treating the lower bound and upper bounds as 'long' data types than 64 bit generic data types in both machine architectures.

To describe more ...

lets consider a simple 42 bit number that is to be generated in the UPER format.

Timestamp ::= INTEGER (0..4398046511103)

When generated with the asn1c on the 32 bit X86 processor, it produces the Timestamp as a long variable. As the long variable is of length 4 bytes on the 32 bits architecture, the encoding always a failure when the integer value goes more than INT_MAX.

I'm working with this in PR #129
Would be appreciated if you could test the changes I have made to see if it will solve your issues.
