This adds a new adapter and an example for using hiredis with the ivykis
async I/O library.

Not all code using hiredis can compile using '-std=c99', and/or not all users are able to easily make that change to the build process of various open-source projects, so it is more pragmatic to choose a different identifier that does not impose this requirement.
When an asynchronous hiredis connection subscribes to a Pub/Sub channel
and gets an error, and in other related conditions, the function
redisProcessCallbacks() enters a code path where the link is
disconnected, however the function returns before freeing the allocated
reply object. This causes a memory leak. The memory leak was trivial to
trigger in Redis Sentinel, which uses hiredis, every time we tried to
subscribe to an instance that required a password, in case the Sentinel
was configured either with the wrong password or without password at
all. In this case, the -AUTH error caused the leaking code path to be
executed.
Originally implemented by @abedra as part of #306.
In case a write or read times out, we force an error state, because we
can't guarantuee that the next read will get the right data.
Instead we need to reconnect to have a clean-state connection, which is
now easily possible with this method.
Attempting to use the install target before the make target works fine,
except for the missing pkgconfig file. Adding that file to the
dependencies for the install target to make sure it gets created first.
Due to the various processors going over the command, we need more
escaping.
1) Make parses it, so $${libdir} becomes ${libdir}
2) 'shell' parses it for the 'echo command', whereas echo ${libdir}
would be an empty string; escape it as \${libdir} to ensure we get what
we want.
Closes#312
Major fix:
- `make install` now works properly
Minor fix:
- `make test` now works after `make 32bit` on a 64-bit platform
- added more automated travis tests
This replaces the old intlen() implementation with a slightly
faster way of counting digits.
Implementation taken from the same place where digits10() in
redis/src/util.c came from.
The old 'intlen' allowed negative inputs, but no usage in hiredis
was passing negative numbers, so that ability is removed. Also,
the new implementation can count higher (uint64_t) instead of
limited to just int as before.

This change also makes the test stop hanging for 10 to 30 seconds
waiting for the resolver to timeout. Now the resolver immediately
sees the hostname is bad and returns error without waiting for timeout.
