- 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

errno is never set to zero by any system call or library function,
and it's programmer's resposibility to reset it before doing checks.
Otherwise the error might be misleading.

The whole remote_ctx is inserted into the cache and sockaddr_storage contains
both address and port.

This may fix#565
It is not recommended to compare two structs via memcmp although they have been
memset to 0.
Added two helper functions to compare sockaddr_storage, one for address only and
the other one takes port into account.
These two functions are based on Unbound version in util/net_help.c, and
comform needs of shadowsocks-libev.

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

Note:
- ChaCha20 with an extended (96 bit) nonce and a 32-bit counter has
been implemented as crypto_stream_chacha20_ietf() from LibSodium 1.0.4
- The name of new cipher is "chacha20-ietf"
