[FL-3097] fbt, faploader: minimal app module implementation (#2420)

Browse Source 
* fbt, faploader: minimal app module implementation
* faploader, libs: moved API hashtable core to flipper_application
* example: compound api
* lib: flipper_application: naming fixes, doxygen comments
* fbt: changed `requires` manifest field behavior for app extensions
* examples: refactored plugin apps; faploader: changed new API naming; fbt: changed PLUGIN app type meaning
* loader: dropped support for debug apps & plugin menus
* moved applications/plugins -> applications/external
* Restored x bit on chiplist_convert.py
* git: fixed free-dap submodule path
* pvs: updated submodule paths
* examples: example_advanced_plugins.c: removed potential memory leak on errors
* examples: example_plugins: refined requires
* fbt: not deploying app modules for debug/sample apps; extra validation for .PLUGIN-type apps
* apps: removed cdefines for external apps
* fbt: moved ext app path definition
* fbt: reworked fap_dist handling; f18: synced api_symbols.csv
* fbt: removed resources_paths for extapps
* scripts: reworked storage
* scripts: reworked runfap.py & selfupdate.py to use new api
* wip: fal runner
* fbt: moved file packaging into separate module
* scripts: storage: fixes
* scripts: storage: minor fixes for new api
* fbt: changed internal artifact storage details for external apps
* scripts: storage: additional fixes and better error reporting; examples: using APP_DATA_PATH()
* fbt, scripts: reworked launch_app to deploy plugins; moved old runfap.py to distfap.py
* fbt: extra check for plugins descriptors
* fbt: additional checks in emitter
* fbt: better info message on SDK rebuild
* scripts: removed requirements.txt
* loader: removed remnants of plugins & debug menus
* post-review fixes

* Acurite 592TXR Temperature Humidity sensor decoder
* Message Type 0x04, 7 bytes
* | Byte 0 | Byte 1 | Byte 2 | Byte 3 | Byte 4 | Byte 5 | Byte 6 |
* | --------- | --------- | --------- | --------- | --------- | --------- | --------- |
* | CCII IIII | IIII IIII | pB00 0100 | pHHH HHHH | p??T TTTT | pTTT TTTT | KKKK KKKK |
* - C: Channel 00: C, 10: B, 11: A, (01 is invalid)
* - I: Device ID (14 bits)
* - B: Battery, 1 is battery OK, 0 is battery low
* - M: Message type (6 bits), 0x04
* - T: Temperature Celsius (11 - 14 bits?), + 1000 * 10
* - H: Relative Humidity (%) (7 bits)
* - K: Checksum (8 bits)
* - p: Parity bit
* Notes:
* - Temperature
* - Encoded as Celsius + 1000 * 10
* - only 11 bits needed for specified range -40 C to 70 C (-40 F - 158 F)
* - However 14 bits available for temperature, giving possible range of -100 C to 1538.4 C
* - @todo - check if high 3 bits ever used for anything else

* - I: Random Device Code: changes with battery reset

* - T: Temperature: 12 Bit 2's complement, scaled by 10, range-50.0 C (-50.1 shown as Lo) to +70.0 C (+70.1 C is shown as Hi)
* - X: Checksum, xor shifting key per byte
* Humidity:
* - the working range is 20-95 %
* - if "LL" in display view it sends 10 %
* - if "HH" in display view it sends 110%
* Checksum:
* Per byte xor the key for each 1-bit, shift per bit. Key list per bit, starting at MSB:

* - inFactory NC-3982-913/NX-5817-902, Pearl (for FWS-686 station)
* - nor-tec 73383 (weather station + sensor), Schou Company AS, Denmark
* - DAY 73365 (weather station + sensor), Schou Company AS, Denmark
* Known brand names: inFactory, nor-tec, GreenBlue, DAY. Manufacturer in China.
* Transmissions includes an id. Every 60 seconds the sensor transmits 6 packets:

* - u: unknown; (sometimes set at power-on, but not always)
* - b: battery low; flag to indicate low battery voltage
* - h: Humidity; BCD-encoded, each nibble is one digit, 'A0' means 100%rH
* - t: Temperature; in °F as binary number with one decimal place + 90 °F offset

* LaCrosse TX 433 Mhz Temperature and Humidity Sensors.
* - Tested: TX-7U and TX-6U (Temperature only)
* - Not Tested but should work: TX-3, TX-4
* - also TFA Dostmann 30.3120.90 sensor (for e.g. 35.1018.06 (WS-9015) station)
* - also TFA Dostmann 30.3121 sensor
* Protocol Documentation: http://www.f6fbb.org/domo/sensors/tx3_th.php
* Message is 44 bits, 11 x 4 bit nybbles:
* [00] [cnt = 10] [type] [addr] [addr + parity] [v1] [v2] [v3] [iv1] [iv2] [check]
* Notes:
* - Zero Pulses are longer (1,400 uS High, 1,000 uS Low) = 2,400 uS
* - One Pulses are shorter ( 550 uS High, 1,000 uS Low) = 1,600 uS
* - Sensor id changes when the battery is changed
* - Primary Value are BCD with one decimal place: vvv = 12.3
* - Secondary value is integer only intval = 12, seems to be a repeat of primary
* This may actually be an additional data check because the 4 bit checksum
* and parity bit is pretty week at detecting errors.
* - Temperature is in Celsius with 50.0 added (to handle negative values)
* - Humidity values appear to be integer precision, decimal always 0.
* - There is a 4 bit checksum and a parity bit covering the three digit value
* - Parity check for TX-3 and TX-4 might be different.
* - Msg sent with one repeat after 30 mS
* - Temperature and humidity are sent as separate messages
* - Frequency for each sensor may be could be off by as much as 50-75 khz
* - LaCrosse Sensors in other frequency ranges (915 Mhz) use FSK not OOK
* so they can't be decoded by rtl_433 currently.
* - Temperature and Humidity are sent in different messages bursts.

* The data is grouped in 9 nibbles

* - type: 4 bit fixed 1001 (9) or 0110 (5)
* - id: 8 bit a random id that is generated when the sensor starts, could include battery status
* the same batteries often generate the same id
* - flags(3): is 1 when the battery is low, otherwise 0 (ok)
* - flags(2): is 1 when the sensor sends a reading when pressing the button on the sensor
* - flags(1,0): the channel number that can be set by the sensor (1, 2, 3, X)
* - temp: 12 bit signed scaled by 10

*
* Ambient Weather TX-8300 (also sold as TFA 30.3211.02).
* 1970us pulse with variable gap (third pulse 3920 us).
* Above 79% humidity, gap after third pulse is 5848 us.
* - Bit 1 : 1970us pulse with 3888 us gap
* - Bit 0 : 1970us pulse with 1936 us gap
* 74 bit (2 bit preamble and 72 bit data => 9 bytes => 18 nibbles)
* The preamble seems to be a repeat counter (00, and 01 seen),
* the first 4 bytes are data,
* the second 4 bytes the same data inverted,
* the last byte is a checksum.
* Preamble format (2 bits):
* [1 bit (0)] [1 bit rolling count]
* Payload format (32 bits):
* HHHHhhhh ??CCNIII IIIITTTT ttttuuuu
* - H = First BCD digit humidity (the MSB might be distorted by the demod)
* - h = Second BCD digit humidity, invalid humidity seems to be 0x0e
* - ? = Likely battery flag, 2 bits
* - C = Channel, 2 bits
* - N = Negative temperature sign bit
* - I = ID, 7-bit
* - T = First BCD digit temperature
* - t = Second BCD digit temperature
* - u = Third BCD digit temperature
* The Checksum seems to covers the 4 data bytes and is something like Fletcher-8.
