* Replace multiple potentially non aligned pointer dereference (#4855)
First step to fix some Crypto crashes or strange behaviors
* Makes the two Crypto byte buffers aligned (#4855)

* Add MESHTASTIC_PKC_OVERHEAD
* compare to MESHTASTIC_HEADER_LENGTH

* Re-implement PKI from #1509
co-authored-by: edinnen <ethanjdinnen@protonmail.com>
* Set the key lengnth to actually make PKI work.
* Remove unused variable and initialize keys to null
* move printBytes() to meshUtils
* Don't reset PKI key son reboot unless needed.
* Remove double encryption for PKI messages
* Cleanup encrypt logic
* Add the MESHTASTIC_EXCLUDE_PKI option, and set it for minimal builds. Required for STM32 targets for now.
* Use SHA-256 for PKI key hashing, and add MESHTASTIC_EXCLUDE_PKI_KEYGEN for STM32
* Fix a crash when node is null
* Don't send PKI encrypted packets while licensed
* use chIndex 8 for PKI
* Don't be so clever, that you corrupt incoming packets
* Pass on channel 8 for now
* Typo
* Lock keys once non-zero
* We in fact need 2 scratch buffers, to store the encrypted bytes, unencrypted bytes, and decoded protobuf.
* Lighter approach to retaining known key
* Attach the public key to PKI decrypted packets in device memory
* Turn PKI back off for STM32 :(
* Don't just memcp over a protobuf
* Don't PKI encrypt nodeinfo packets
* Add a bit more memory logging around nodeDB
* Use the proper macro to refer to NODENUM_BROADCAST
* Typo fix
* Don't PKI encrypt ROUTING (naks and acks)
* Adds SecurityConfig protobuf
* Add admin messages over PKI
* Disable PKI for the WIO-e5
* Add MINIMUM_SAFE_FREE_HEAP macro and set to safe 1.5k
* Add missed "has_security"
* Add the admin_channel_enabled option
* STM32 again
* add missed configuration.h at the top of files
* Add EXCLUDE_TZ and RTC
* Enable PKI build on STM32 once again
* Attempt 1 at moving PKI to aes-ccm
* Fix buffers for encrypt/decrypt
* Eliminate unused aes variable
* Add debugging lines
* Set hash to 0 for PKI
* Fix debug lines so they don't print pointers.
* logic fix and more debug
* Rather important typo
* Check for short packets before attempting decrypt
* Don't forget to give cryptoEngine the keys!
* Use the right scratch buffer
* Cleanup
* moar cleanups
* Minor hardening
* Remove some in-progress stuff
* Turn PKI back off on STM32
* Return false
* 2.5 protos
* Sync up protos
* Add initial cryptography test vector tests
* re-add MINIMUM_SAFE_FREE_HEAP
* Housekeeping and comment fixes
* Add explanatory comment about weak dh25519 keys

* Event mode: Enforce reliable hop limit
* Event mode: Short circuit wantsLink on MQTT for default broker address
* Just enforce at channels level since everything uses this
* For events never forward packets with excessive hop_limit
* In EVENT_MODE, don't respond with hop_limit set more then the configured max.
* Correct hop_start when correcting hop_limit in event mode.
* Make EVENT_MODE work from userPrefs.h
* Event mode: Disallow Router or Repeater roles

* Make sure to call randomSeed() on esp32
* Randomize the top 22 bits of the Message ID
* Make it clear that we are not calling randomSeed() on purpose

* New UUID
* New log radio characteristic with LogRecord protobuf
* LogRecord
* Merge derp
* How did you get there
* Trunk
* Fix length
* Remove assert
* Add MaxNodes to Native
* It compiles...
* Convert nodedb to use new
* Closer but still broken.
* Finally working
* Remove unintended lines
* Don't include a pointer
* Capitalization matters.
* avoid rename in protocol regen
* When trimming the nodeDB, start with a cleanup
* Remove extra cleanupMeshDB() call for now

* Set `hop_start` in header to determine how many hops each packet traveled
* Set hopLimit of response according to hops used by request
* Identify neighbors based on `hopStart` and `hopLimit`
* NeighborInfo: get all packets and assume a default broadcast interval
* Add fail-safe in case node in between is running modified firmware
* Add `viaMQTT` and `hopsAway` to NodeInfo
* Replace `HOP_RELIABLE` with hopStart for repeated packet

Such that direct message to MQTT node gets published and we get rid of always rebroadcasting when MQTT is enabled
Co-authored-by: Ben Meadors <benmmeadors@gmail.com>
* fix: allow MQTT `encryption_enabled` with `json_enabled`
* fix: copy decoded MeshPacket and release memory after use
* fix: use `packetPool` allocCopy and release methods

* Mark packets received via MQTT and add option to ignore them
* Don't send packets received via MQTT back into MQTT
Generate implicit ACK for packets we as an MQTT gateway sent

* Fix compression: encode to bytes after `decoded` is modified
* Change payload size to decompressed length
