[patch] compiler warning in saslauthd/auth_pam.c

[Matt Selsky]

This fixed a compiler warning while building auth_pam.c on Solaris 9.

gcc -DHAVE_CONFIG_H -DSASLAUTHD_CONF_FILE_DEFAULT=\"/opt/cyrus-sasl-2.1.10/etc/saslauthd.conf\" -I. -I../../../src/saslauthd -I.. -I../../../src/saslauthd/include    -g -O2 -c ../../../src/saslauthd/auth_pam.c
../../../src/saslauthd/auth_pam.c: In function `auth_pam':
../../../src/saslauthd/auth_pam.c:196: warning: assignment from incompatible pointer type

I see on Linux that struct pam_conv's member conv is declared with the 
2nd argument const.  Solaris doesn't declare the argument const.
