Remove old struct definition

typedef struct log_content_ctx log_content_ctx_t;
Separate host and port into separate strings Store host and port in separate strings internally and get rid of the [host]:port representation where separate host and port would be cleaner. This includes the following user-visible changes: - Generated filenames that contain host and port, such as by -S and -F %d and %s, now use a host,port format instead of [host]:port. - Connect log now uses separate fields for host and port.

Introduce privilege separation architecture Fork into a monitor parent process and an actual proxy child process, communicating over AF_UNIX sockets. Certain privileged operations are performed through the privileged parent process, like opening log files or listener sockets, while all other operations happen in the child process, which can now drop its privileges without side-effects for log file opening and other privileged operations. This is also a preparation for -l/-L logfile reopening through SIGUSR1. This means that -S and -F are no longer relative to chroot() if used with -j. This is a deliberate POLA violation.

Move cert writer to logger thread using privsep Make -w and -W work in conjunction with dropping privileges and chrooting by moving the cert writer code to a separate logger thread and using the privsep framework to open the files if they do not exist already. Issue: #70

int log_cert_submit(const char *, X509 *) NONNULL(1,2) WUNRES;
Always explicitly name the non-null arguments Always explicitly name which arguments are non-null, even if all arguments are non-null. This is to avoid bugs where newly added arguments are automatically non-null by accident, possibly leading to optimisation errors. This also fixes a few potential errors related to non-null arguments; specifically it prevents the compiler optimising away a test for sni being NULL in cachedsess_mkkey().
