* Adds an indirection to every allocation/deallocation to allow users to
plug in ones of their choosing (use custom functions, jemalloc, etc).
* Gracefully handle OOM everywhere in hiredis. This should make it possible
for users of the library to have more flexibility in how they handle such situations.
* Changes `redisReaderTask->elements` from an `int` to a `long long` to prevent
a possible overflow when transferring the task elements into a `redisReply`.
* Adds a configurable `max elements` member to `redisReader` that defaults to
2^32 - 1. This can be set to "unlimited" by setting the value to zero.
* Remove nested depth limitation.
This commit removes the nested multi-bulk depth limitation of 7.
We do this by switching to pointer to pointer indirection and
growing the stack in chunks when needed.
See: #794, #421
* Fix linker problems when building with SSL enabled on OSX
* Corrects `HIREDIS_SSL=ON` to `USE_SSL=ON` so we test building with
SSL enabled on travis.
* Add CMake package configuration so hiredis can be more easily included in
other projects.
* Fixes hiredis_ssl such that it compiles and works in windows

Unit tests in Windows and a Windows timeout fix
This commit gets our unit tests compiling and running on Windows as well as removes a duplicated `timeval` -> `DWORD` conversion logic in sockcompat.c
There are minor differences in behavior between Linux and Windows to note:
1. In Windows, opening a non-existent hangs forever in WSAPoll whereas
it correctly returns with a "Connection refused" error on Linux.
For that reason, I simply skip this test in Windows.
It may be related to this known issue:
https://daniel.haxx.se/blog/2012/10/10/wsapoll-is-broken/
2. Timeouts are handled slightly differently in Windows and Linux.
In Linux, we intentionally set REDIS_ERR_IO for connection
timeouts whereas in Windows we set REDIS_ERR_TIMEOUT. It may be
prudent to fix this discrepancy although there are almost certainly
users relying on the current behavior.
Housekeeping
* Check for C++ (#758, #750)
* Include `alloc.h` in `make install` and `cmake`
* Add a `.def` file for Windows (#760)
* Include allocation wrappers referenced in adapter headers
* Fix minor syntax errors and typos in README
* Fix CI in Windows by properly escaping arguments (#761)
We currently perform a NULL check in redisGetReply and don't push the
reply back to the caller, but we don't free any reply meaning that this
will leak memory:
redisGetReply(context, NULL);
This change simply frees the reply if we were passed NULL.
Addresses #740
Coverity scans found that the should_log logic in sslLogCallback
is not working as expected because the variable is not correctly
initialised (the conditional code before logging always sets the
value to 1, which it already is).
Useful when hiredis is used as a CMake dependency in other projects and
added via add_subdirectory(). With DISABLE_TESTS on, `make test` in the
parent project won't run hiredis tests.
We should not attempt to keep the context and re-establish the
TLS connection for several reasons:
1. Maintain symmetry between redisConnect() and redisReconnect(), so in
both cases an extra step is required to initiate SSL.
2. The caller may also wish to reconfigure the SSL session and needs a
chance to do that.
3. It is not a practical thing to do on an async non-blocking connection
context.
