jpirnay 4104fa8102 fix: Fix bootloop logging crash (#1357)
## Summary

* **What is the goal of this PR?** On a cold boot (or after a crash that
corrupts RTC RAM), logHead contains garbage. Then addToLogRingBuffer
does: ``strncpy(logMessages[logHead], message, MAX_ENTRY_LEN - 1); ``
With garbage logHead, this computes a completely invalid address. The %
MAX_LOG_LINES guard on line 16 only runs after the bad store, which is
too late. The fix is to clamp logHead before use.

## Additional Context

* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
  specific areas to focus on).

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into the executable file.

The source code of each library should be placed in a separate directory
("lib/your_library_name/[Code]").

For example, see the structure of the following example libraries `Foo` and `Bar`:

|--lib
|  |
|  |--Bar
|  |  |--docs
|  |  |--examples
|  |  |--src
|  |     |- Bar.c
|  |     |- Bar.h
|  |  |- library.json (optional. for custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
|  |
|  |--Foo
|  |  |- Foo.c
|  |  |- Foo.h
|  |
|  |- README --> THIS FILE
|
|- platformio.ini
|--src
   |- main.c

Example contents of `src/main.c` using Foo and Bar:
```
#include <Foo.h>
#include <Bar.h>

int main (void)
{
  ...
}

```

The PlatformIO Library Dependency Finder will find automatically dependent
libraries by scanning project source files.
