* numhash.h - (telephone) number storing/hashing system
*
* Kalle Marjola 2000 for project Kannel
*
* !!! NOTE NOTE NOTE !!!
*
* Phone number precision is limited according to sizeof(long long)
* in host machine. that is usually either 32 or 64 bits. In a
* case of 32 bit longs, only last 19 digits are checked, otherwise
* last 38 digits. This means that in some places several numbers
* might map to same hash entry, and thus some caution is needed
* specially with telephone number black lists
*
* USAGE:
* the system is not very dynamic; if you want to resize the table
* or hash, you must first nuke all old data and then recreate it
*
* MEMORY NEEDED: (approximated)
*
* 2* (sizeof(long long)+sizeof(void *)) bytes per number
