Initialize the logger as soon as possible and log by default to stderr. With this, some (common?) errors are printed early instead of ending up in syslog. # NB: this is in configless mode % ./gmid -p 80 [2021-07-07 11:05:57] bind: Address already in use % ./gmid -p 81 [2021-07-07 11:13:53] bind: Permission denied %

patch from Anna "CyberTailor" It's handy for helpers like ebuild's use_enable. (the sandbox is still always enabled by default)

patch from Anna "CyberTailor"

Initial patch from Anna "CyberTailor", tweaked by me (drop guessing_* and always append CFLAGS)

but still try to autodetect with pkg-config if they aren't provided. Passing CFLAGS/LDFLAGS from the command line will still override the guessed ones.

we need to delete the events associated with the backends, otherwise the server process won't ever quit. Here, we add a pending counter to every backend and shut down immediately if they aren't handling any client; otherwise we try to close them as soon as possible (i.e. when they close the connection to the last connected client.)

our stderr could have been sent to the logger process, so it may be invalid. Furthermore, in the future we may want to capture also the stderr of the processes.
