[svn-r3993] Purpose:
    Bug fix for Pablo integration
Description:
    Several API functions were using FUNC_ENTER, without using FUNC_LEAVE,
    HRETURN or HRETURN_ERROR to leave the function.  (Using "plain" 'return'
    statements instead).
Solution:
    Changed return statements to FUNC_LEAVE, HRETURN or HRETURN_ERROR, as
    appropriate.
Platforms tested:
    FreeBSD 4.3 (hawkwind)
