build.log.entry: Creates a log entry as a single `data.frame` row containing all relevant logging information in columns

Description

The serverity level should correspond to the condition class.

build.log.entry(
  timestamp,
  severity,
  msg.text,
  execution.context.msg,
  call.stack,
  dump.file.name,
  omit.call.stack.items = 0
)

An object of class tryCatchLog.log.entry and data.frame and the following columns:

timestamp - creation date and time of the logging entry
severity - the serverity level of the log entry (ERROR, WARN, INFO etc.)
msg.text - the message text of the log entry
compact.stack.trace - the short stack trace containing only entries with source code references down to line of code that has thrown the condition
full.stack.trace - the full stack trace with all calls down to the line of code that has thrown the condition (including calls to R internal functions and other functions even when the source code in not available).
dump.file.name - name of the created dump file (if any)

timestamp: logging timestamp as POSIXct (normally by calling Sys.time)
severity: severity level of the log entry ((ERROR, WARN, INFO etc.)
msg.text: Logging message (e. g. error message)
execution.context.msg: a text identifier (eg. the PID or a variable value) that will be appended to msg.text for catched conditions. Must be a character or an error is thrown.
call.stack: a call stack created by sys.calls
dump.file.name: name of the created dump file (leave empty if the tryCatchLog argument write.error.dump.file is FALSE)
omit.call.stack.items: the number of stack trace items to ignore (= last x calls) in the passed call.stack since they are caused by using tryCatchLog
