Trafodion 2916
**the root cause**: the allocating size of str is determined by max field
length + 128(here is 1500+128), but during loading, str will be filled with
actual field data exceeding this size(here maybe 2000 characters) if str
overflow the client app will crash.
**solution**: increase the size of str to the size of one-time
fread(default is 262144). there is still a risk of a crash when a user provides
an incredibly large size of an invalid field.
**additional fix**: also fix other same type potential bugs in Oload2 and
OloadJason.
