Previously invalid configuration errors were not very specific and in some cases hard to understand.

* Adds ASYNC and SYNC arguments to SCRIPT FLUSH
* Adds SYNC argument to FLUSHDB and FLUSHALL
* Adds new config to control the default behavior of FLUSHDB, FLUSHALL and SCRIPT FLUASH.
the new behavior is as follows:
* FLUSH[ALL|DB],SCRIPT FLUSH: Determine sync or async according to the
value of lazyfree-lazy-user-flush.
* FLUSH[ALL|DB],SCRIPT FLUSH ASYNC: Always flushes the database in an async manner.
* FLUSH[ALL|DB],SCRIPT FLUSH SYNC: Always flushes the database in a sync manner.

The prefix is changed from `RM_` to `module` on the following
internal functions, to prevent them from appearing in the API docs:
RM_LogRaw -> moduleLogRaw
RM_FreeCallReplyRec -> moduleFreeCallReplyRec
RM_ZsetAddFlagsToCoreFlags -> moduleZsetAddFlagsToCoreFlags
RM_ZsetAddFlagsFromCoreFlags -> moduleZsetAddFlagsFromCoreFlags

Fixes markdown formatting errors and some functions not showing
up in the generated documentation at all.
Ruby script (gendoc.rb) fixes:
* Modified automatic instertion of backquotes:
* Don't add backquotes around names which are already preceded by a
backquote. Fixes for example \`RedisModule_Reply\*\` which turning
into \`\`RedisModule_Reply\`\*\` messes up the formatting.
* Add backquotes around types such as RedisModuleString (in addition
to function names `RedisModule_[A-z()]*` and macro names
`REDISMODULE_[A-z]*`).
* Require 4 spaces indentation for disabling automatic backquotes, i.e.
code blocks. Fixes continuations of list items (indented 2 spaces).
* More permissive extraction of doc comments:
* Allow doc comments starting with `/**`.
* Make space before `*` on each line optional.
* Make space after `/*` and `/**` optional (needed when appearing on
its own line).
Markdown fixes in module.c:
* Fix code blocks not indented enough (4 spaces needed).
* Add black line before code blocks and lists where missing (needed).
* Enclose special markdown characters `_*^<>` in backticks to prevent them
from messing up formatting.
* Lists with `1)` changed to `1.` for proper markdown lists.
* Remove excessive indentation which causes text to be unintentionally
rendered as code blocks.
* Other minor formatting fixes.
Other fixes in module.c:
* Remove blank lines between doc comment and function definition. A blank
line here makes the Ruby script exclude the function in docs.

* Change zunionInterDiffGenericCommand to use lookupKeyRead if dstkey is null
* Change zrangeGenericCommand to use lookupKey Write if dstkey isn't null
ZRANGESTORE and UNION, ZINTER, ZDIFF are all new commands (6.2 RC1 and RC2).
In redis 6.0 the ZRANGE was using lookupKeyRead, and ZUNIONSTORE / ZINTERSTORE were using lookupKeyWrite.
So there bugs are introduced in 6.2 and will be resolved before it is released.
the implications of this bug are also not big:
The sole difference between LookupKeyRead and LookupKeyWrite is for command executed on a replica, which are not received from its master client. (for the master, and for the master client on the replica, these two functions behave the same)!

This will allow to use: RedisModule_CreateStringPrintf(ctx, "%s %c %s", "string1", 0, "string2");
On large string, the previous code would incrementally retry to double the output buffer.
now it uses the the return value of snprintf and grows to the right size in one step.
and also avoids an excessive strlen in sdscat at the end.

The bug occurs when 'callback' re-registers itself to a point
in the future and the execution time in non-negligible:
'now' refers to time BEFORE callback was executed and is used
to calculate 'next_period'.
We must get the actual current time when calculating 'next_period'

Turns out this was broken since version 4.0 when we added sds size
classes.
The cluster code uses sds for the receive buffer, and then casts it to a
struct and accesses a 64 bit variable.
This commit replaces the use of sds with a simple reallocated buffer.

When client tracking is enabled signalModifiedKey can increase memory usage,
this can cause the loop in performEvictions to keep running since it was measuring
the memory usage impact of signalModifiedKey.
The section that measures the memory impact of the eviction should be just on dbDelete,
excluding keyspace notification, client tracking, and propagation to AOF and replicas.
This resolves part of the problem described in #8069
p.s. fix took 1 minute, test took about 3 hours to write.
