Fix rlm_totp and add new test suite

[jpereira]

eg:

[jpereira@sugarloaf:freeradius-server.git]$ make
CC src/modules/rlm_totp/rlm_totp.c
LINK build/lib/rlm_totp.la
[jpereira@sugarloaf:freeradius-server.git]$ make test.totp
TOTP-TEST INPUT=now_token_6digits.txt TOKEN=089002 TOTP_GEN_ARGV="-d 6 -D sha1"
TOTP-TEST INPUT=now_token_8digits.txt TOKEN=68089002 TOTP_GEN_ARGV="-d 8 -D sha1"
[jpereira@sugarloaf:freeradius-server.git]$

I'm not clear why this is necessary? The totp module really should only be authenticating users.

I guess that it could go anywhere to authenticate users, but we generally put the pap, chap, etc. authentications into an authenticate section
