Thomas Osterried e489b57205 Major improvements and smaller bugfixes
- feature: option to disable wifi. Saves abt 80mA current
  3 options: 2 alaways on; 1 off if no bluetooth client is connected in between
  60s after boot (watch red oled button; goes off as soon as a
  bt client connects in the boot phase). 0 disable (re-enabl by pressing
  beacon button)
- pseudo csma/cd. ppersist / slottime as we know it from standard
  packet-radio / -APRS
  In loaSend. TODO: better concept with a tx-queue. But this is rather complex,
  because the queue must not grow too large, else we re-send old packts..
- feature to encode altitude in compressed position instead of /A=...
  compressed position can encode course/speed, altitude (and others). Option to
  send course/speed to 0%, 100% or something in between.
  altitude check button is obsolete. Switch off by setting alt ratio to 0.
- cross-digipeating: just for sure, clear rx queue after going back to main
  freq.
- if we are not a digipeater and we have no serial-bt-client, we may let the
  loraChip sleep (axp.setPowerOutPut(AXP192_LDO2, AXP202_OFF)) -> saves current
  (a bit)
- adjust_cpu_freq_to: change CPU frequency. May reduce cpu power consumption
  up to 20 %. Suggesting (and tested with) 80 MHz. USE WITH CARE! I.e.
  40 MHz or 20 MHz did not work with my device (boot phase never ended)
- options to start tncServer and gpsServer (if you don't need them, you
  may not like to expose these tcp ports to your LAN or HAMNET)
- changed preferences.getString(PREFxxxxx) to
  preferences.getString(PREFxxxxx, ""), because if variable is not set,
  the preferences library returns "the variable name itself" - wtf!.
  In the case of PREF_NTP_SERVER, we saw log messages that ntp server
  with fqdn "ntp_server" could not be resolved; it had no impact, because
  it did a failback to the compiled-in default.  Changed call for
  PREF_WIFI_PASSWORD, PREF_AP_PASSWORD, etc.. too.
- wifi-AP: is set to esp_wifi_set_max_tx_power(8) (for lesser power
  consumption of the devie). 8 dBm are too less fore some cases.
  -> New web config for setting max_tx_power in AP- and STA- modes.
- Fix: In mode wifi-client, it did not reconnect if association was lost.
- small improvement for comment-text ratelimiting

BG_RF95.cpp: BG_RF95::SignalDetected feature (needed for pseudo csma/cd)

README

This directory is intended for project header files.

A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.

```src/main.c

#include "header.h"

int main (void)
{
 ...
}
```

Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.

In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.
