Description of problem:
zone2sqlite cannot create a table when table name contain ".", "-" or start with a digit, etc.

Version-Release number of selected component (if applicable):
bind-9.8.2-0.17.rc1.el6.3.x86_64
bind-sdb-9.8.2-0.17.rc1.el6.3.x86_64

How reproducible:
# zone2sqlite
usage: zone2sqlite <zone> <zonefile> <dbfile> <dbtable>

# zone2sqlite domaintest.org m:domaintest.org zones.db domaintest.org
Connecting to 'zones.db'
DROP TABLE domaintest.org 
CREATE TABLE domaintest.org (NAME TEXT, TTL INTEGER, RDTYPE TEXT, RDATA TEXT) 
CREATE TABLE domaintest.org failed: unknown database domaintest

# zone2sqlite 0-255.1.168.192.in-addr.arpa m:0-255.1.168.192.in-addr.arpa zones.db 0-255.1.168.192.in-addr.arpa
Connecting to 'zones.db'
DROP TABLE 0-255.1.168.192.in-addr.arpa 
CREATE TABLE 0-255.1.168.192.in-addr.arpa (NAME TEXT, TTL INTEGER, RDTYPE TEXT, RDATA TEXT) 
CREATE TABLE 0-255.1.168.192.in-addr.arpa failed: near "0": syntax error

# zone2sqlite 0-255.1.168.192.in-addr.arpa m:0-255.1.168.192.in-addr.arpa zones.db rev_0-255.1.168.192.in-addr.arpa
Connecting to 'zones.db'
DROP TABLE rev_0-255.1.168.192.in-addr.arpa 
CREATE TABLE rev_0-255.1.168.192.in-addr.arpa (NAME TEXT, TTL INTEGER, RDTYPE TEXT, RDATA TEXT) 
CREATE TABLE rev_0-255.1.168.192.in-addr.arpa failed: near "-": syntax error

Additional info:
1. Table can be created with dummy names and renamed after.
2. named-sdb seems to work fine with table names containing ".", "-" or starting with a digit.
3. Fixing the bug is trivial.
