* . name convention: upgrade-X.Y-enter.xsl,
* when not present: upgrade-enter.xsl

a smart way (no reliance on formatting string + arguments being
always specified as ["%s", purposeful_string], as it can also be
["%s: %s", some_prefix, purposeful_string] etc. so every argument
pertaining %s specifier is investigated), and if such a mark found,
the respective level is determined and, when the messages are to go
to the native logs, the mark itself gets dropped
(by the means of string shift).
NOTE: whether the native logging is the right sink is decided per
the ctx parameter -- NULL denotes this case, otherwise it
carries a pointer to the numeric expression of the desired
target logging level (messages with higher level will be
suppressed)
NOTE: on some architectures, this string shift may not have any
effect, but that's an acceptable tradeoff
