const parameter dropped in psMemProblemCallback

[David.Robbins@…]

the psLib SDRS rev. 15 has sec. 2.4.5.2 defining psMemProblemCallback now as,

typedef void (*psMemProblemCallback) (psMemBlock *ptr, char *filename, usigned
int lineno);

I believe the 2nd argument should still be 'const char *filename'. The private
functions such as p_psAlloc, p_psFree, etc. still use 'const' so unless there
is a reason for this change, repeatedly casting filename as a psPtr just makes
the code "ugly". Please advise.

Agreed. Fixed.
