Log Message:
Bug Description: Need to address 64-bit compiler warnings - part 1
Reviewed by: nhosoi (Thanks!)
Fix Description: The intptr_t and uintptr_t are types which are defined as integer types that are the same size as the pointer (void *) type.  On the platforms we currently support, this is the same as long and unsigned long, respectively (ILP32 and LP64).  However, intptr_t and uintptr_t are more portable.  These can be used to assign a value passed as a void * to get an integer value, then "cast down" to an int or PRBool, and vice versa.  This seems to be a common idiom in other applications where values must be passed as void *.
For the printf/scanf formats, there is a standard header called inttypes.h which defines formats to use for various 64 bit quantities, so that you don't need to figure out if you have to use %lld or %ld for a 64-bit value - you just use PRId64 which is set to the correct value.  I also assumed that size_t is defined as the same size as a pointer so I used the PRIuPTR format macro for size_t.
I removed many unused variables and some unused functions.
I put parentheses around assignments in conditional expressions to tell the compiler not to complain about them.
I cleaned up some #defines that were defined more than once.
I commented out some unused goto labels.
Some of our header files shared among several source files define static variables.  I made it so that those variables are not defined unless a macro is set in the source file.  This avoids a lot of unused variable warnings.
I added some return values to functions that were declared as returning a value but did not return a value.  In all of these cases no one was checking the return value anyway.
I put explicit parentheses around cases like this: expr || expr && expr - the && has greater precedence than the ||.  The compiler complains because it wants you to make sure you mean expr || (expr && expr), not (expr || expr) && expr.
I cleaned up several places where the compiler was complaining about possible use of uninitialized variables.  There are still a lot of these cases remaining.
There are a lot of warnings like this:
lib/ldaputil/certmap.c:1279: warning: dereferencing type-punned pointer will break strict-aliasing rules
These are due to our use of void ** to pass in addresses of addresses of structures.  Many of these are calls to slapi_ch_free, but many are not - they are cases where we do not know what the type is going to be and may have to cast and modify the structure or pointer.  I started replacing the calls to slapi_ch_free with slapi_ch_free_string, but there are many many more that need to be fixed.
The dblayer code also contains a fix for https://bugzilla.redhat.com/show_bug.cgi?id=463991 - instead of checking for dbenv->foo_handle to see if a db "feature" is enabled, instead check the flags passed to open the dbenv.  This works for bdb 4.2 through bdb 4.7 and probably other releases as well.
