* Put guard pages next to fast alloc memory
I verified that we can now detect #6753 without creating tons of
threads.
* Use pageSize instead of 4096
* Don't include mmapInternal for windows
Changing `memory` option to limit resident memory instead of virtual memory, in config file and fdbserver/fdbbackup/fdbcli command-line argument. Since `rlimit` doesn't support limiting virtual memory, the current implementation have both of fdbmonitor and the fdbserver/fdbbackup process checking process RSS periodically and kill and restart the process if the limit is exceeded.
Adding a new `memory_vsize` option to limit virtual memory, if backward-compatible behavior is desired.

* Introduce BlobCipher interface and cipher caching interface
diff-3: Update the code to avoid deriving encryption key periodically.
Implement EncyrptBuf interface to limit memcpys.
Improve both unit test and simulation to better code coverage.
diff-2: Add specific error code for OpenSSL AES call failures
diff-1: Update encryption scheme to AES-256-CTR. Minor
updates to Header to capture more information.
Major changes proposed are:
1. Introduce encyrption header format.
2. Introduce a BlobCipher cipher key representation encoding
following information: baseCipher details, derived encryption cipher
details, creationTime and random salt.
3. Introduce interface to support block cipher encrytion and decrytion
operations. Encyrption populates encryption header allowing client to
persist them on-disk, this header is then read allowing decryption
on reads.
4. Introduce interface to allow in-memory caching of cipher keys. The
cache allowing mapping of "encryption domain" -> "base cipher id" ->
"derived cipher keys" (3D hash map). This cache interface will be used
by FDB processes participating in encryption to cache recently used
ciphers (performance optimization).
Testing:
1. Unit test to validate caching interface.
2. Update EncryptionOps simulation test to validate block cipher
operations.
MacOS warnings are format warnings, e.g., `format specifies type 'long' but the argument has type 'Version' (aka 'long long')`.
Windows warnings are `ACTOR does not contain a wait() statement`.

* Upgrade AES 128 GCM -> AES 256, StreamCipher code refactor
Major changes proposed are:
1. Refactor StreamCipher code to enable instantiation of
multiple encryption keys. However, code still retains
a globalEncryption key semantics used in Backup file
encryption usecase.
2. Enhance StreamCipher to provide HMAC signature digest
generation. Further, the class implements HMAC encryption
key derivation function.
3. Upgrade StreamCipher to use AES 256 GCM mode from currently
supported AES 128 GCM mode.
Note: The code changes the encryption key size, however, the
feature is NOT currently in use, hence, should be OK.
3. Add EncryptionOps validation and benchmark toml supported
workload, it does the following:
a. Allow user to configure encrypt-decrypt of a fixed size
buffer or variable size buffer [100, 512K]
b. Allow user to configure number of interactions of the runs,
in each iteration: generate random data, derive an encryption
key using HMAC SHA256 method, encrypt data and
then decrypt data. It collects following metrics:
i) time taken to derive encryption key.
ii) time taken to encrypt the buffer.
iii) time taken to decrypt the buffer.
iv) total bytes encrypted and/or decrypted
c. Along with stats it basic basic validations on the encrypted
and decrypted buffer
d. On completion for test, records the above mentioned metrics
in trace files.
In unit and simulation testing calls to pthread_setname_np may return errors,
as the threads may complete before calls to setname can be executed. This change
adds better error handling for cases where ENOENT or ESRCH is returned during testing.
Previously the ASSERT_EQ would cause tests to fail if a non-zero return value was encountered.
This change will trace log with a SevWarn when ENOENT or ESRCH is encountered. Otherwise
it will trace with SevError and throw a platform_error.
1. Introduce processDiskReadSeconds and processDiskWriteSeconds, which stands for disk read/write times `since the last logging`. They can only be obtained on Linux and macOS, and will be 0 on Windows and FreeBSD;
2. Rename `busyTicks` to `IOMilliSecs`;
3. On FreeBSD, the metrics should be collected among all devices.
1. Add a trace event when a database is created and move the cluster file / connection string from ClientStart to the new trace event
2. Add a detail for the path to the image being loaded
3. Add a detail for whether a client library is primary or not
4. Set a thread name for each external client thread that includes the release version
