The proposal to merge ~dirk.zimoch/epics-base:chfPluginImprovements into epics-base:7.0 has been updated.

Description changed to:

1. Allow string arguments with arbitrarily long strings.
In addition to the chfPluginArgString argument type which works on fixed size char array members, chfPluginArgStringAlloc works on char* members. It performs the following actions:
* If a chfPluginArgStringAlloc is provided by the user, the char* member is first NULLed, then filled with a dynamically allocated string (which may fail due to memory shortage)
* If the same char* member may be provided multiple times (maybe under different names), the old value is freed before a new value is written.
* When the structure is released (before freePvt is called), the allocated strings are automatically freed and the char* member NULLed.
* If the parameter is optional and not provided my the user, the pointer is left untouched, allowing to initialize the char* member with a static string as a default value.
2. Allow short forms for filters with 1 or 0 parameters
* If only 1 parameter is required, {filter:value} can be used instead of {filter:{parameter:value}}
* If no parameter is requires, {filter} can be used instead of {filter:{}}
3. Documentarion changed: Use JSON5 features in examples.
