Scope of the changes:
- updated example modules to reference Valkey vs Redis in variable names
- updated tests to use valkeymodule.h
- updated vars in tests/modules to use valkey vs redis in variable names
Summary of the testing:
- ran make for all modules, loaded them into valkey-server and tested
commands
- ran make for test/modules
- ran make test for the entire codebase

Writable replicas now no longer use the values of expired keys. Expired keys are
deleted when lookupKeyWrite() is used, even on a writable replica. Previously,
writable replicas could use the value of an expired key in write commands such
as INCR, SUNIONSTORE, etc..
This commit also sorts out the mess around the functions lookupKeyRead() and
lookupKeyWrite() so they now indicate what we intend to do with the key and
are not affected by the command calling them.
Multi-key commands like SUNIONSTORE, ZUNIONSTORE, COPY and SORT with the
store option now use lookupKeyRead() for the keys they're reading from (which will
not allow reading from logically expired keys).
This commit also fixes a bug where PFCOUNT could return a value of an
expired key.
Test modules commands have their readonly and write flags updated to correctly
reflect their lookups for reading or writing. Modules are not required to
correctly reflect this in their command flags, but this change is made for
consistency since the tests serve as usage examples.
Fixes#6842. Fixes#7475.
APIs added for these stream operations: add, delete, iterate and
trim (by ID or maxlength). The functions are prefixed by RM_Stream.
* RM_StreamAdd
* RM_StreamDelete
* RM_StreamIteratorStart
* RM_StreamIteratorStop
* RM_StreamIteratorNextID
* RM_StreamIteratorNextField
* RM_StreamIteratorDelete
* RM_StreamTrimByLength
* RM_StreamTrimByID
The type RedisModuleStreamID is added and functions for converting
from and to RedisModuleString.
* RM_CreateStringFromStreamID
* RM_StringToStreamID
Whenever the stream functions return REDISMODULE_ERR, errno is set to
provide additional error information.
Refactoring: The zset iterator fields in the RedisModuleKey struct
are wrapped in a union, to allow the same space to be used for type-
specific info for streams and allow future use for other key types.
