Bug Description
Increase the robustness of the routines provided as commands thorugh iocsh, which on Linux/Solaris can cause a segfault and hence abort the IOC.
Additional information:
The following commands when run *after* iocInit cause a Linux IOC to segfault when given no arguments:
astac dba dbap dbb dbc dbd dbgf dbgrep
dbp dbs dbstat dbtgf dbtpf dbtpn tpn
The following commands cause a segfault on Linux when run with no arguments *before* iocInit:
dbLockShowL
dbcar dbp dbs dbstat dbtpn tpn

I've committed a change. The following now seem o.k.: astac, dba, dbap, dbb, dbd, dbgf, dbtgf, dbtpf, dbPvdDump. That leaves dbc, dbgrep, dbp, dbs, dbstat, dbtpn, tpn and dbLockShowLocked, dbcar.
