- GNU treats void* as char* when doing pointer arithmetic, so let's make it clear
- Fix memory leak, save copy from malloc() and pass the original pointer to free()
- minor type mismatches

- Added one macro to avoid dangling pointers
- Added two functions to perform NULL pointer check
since the allocation is not guaranteed by C library, although it
is a rare case, just for sanity
- Add NULL pointer check to brealloc() and bfree() and for sanity as well

code issues found by Clang with
CFLAGS="-Os -Wall -Wextra -Werror=unused-const-variable -Wno-error=unused-parameter"
enabled
The details as follows:
- variable initialization issue, modified them as Clang suggested
- data type mismatch when comparing, fix them either by casting or changing
the data type of index of iterator
- get_sockaddr() in netutils may return -1 thus changed returning type from
size_t to ssize_t, which makes Clang happier
- recvfrom() in udprelay is identical, fix this by creating local variable
for comparison and assign back to buf->len when returning value is acceptable

Fix an error below.
json.c:135:42: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
(state, values_size + ((unsigned long) value->u.object.values), 0)) )
