Michael Paquier 5b0b699f74 Refactor output file handling when forking syslogger under EXEC_BACKEND ... A forked logging collector in EXEC_BACKEND builds passes down file descriptors (or HANDLEs in WIN32) through a command for files to be reopened (for stderr and csvlog). Some of its logic was duplicated, and this commit refactors the code with some wrapper routines for file reopening after forking and fd grabbing when building the command for the fork. While on it, this simplifies a use of "long" in the code, introduced by ab0ba6e to take care of a warning related to MinGW-W64 when mapping a intptr_t to a printed value. "long" is 32-bit long on Windows, and interoperability of Win32 and Win64 ensures that handles are always 32-bit significant, so we can just use "int" for the same result. This also makes the new routines more symmetric. This change makes easier the introduction of new log destinations in the logging collector, and this is not the only piece of refactoring planned. I have tested this change with EXEC_BACKEND on linux, macos, and of course MSVC (both Win32 and Win64), but not MinGW so the buildfarm may have something to say here.
