Update to 1.12.10

• Prevent reading up to 3 bytes beyond the end of a truncated message. This could in principle be an information leak or denial of service on the system bus, but is not believed to be exploitable to crash the system bus or leak interesting information in practice. (fd.o #107332, Simon McVittie)
• Fix build with gcc 8 -Werror=cast-function-type (fd.o #107349, Simon McVittie)
• Fix warning from gcc 8 about suspicious use of strncpy() when populating struct sockaddr_un (fd.o #107350, Simon McVittie)
• Fix a minor memory leak when a DBusServer listens on a new address (fd.o #107194, Simon McVittie)
• Fix an invalid NULL argument to rmdir() if a nonce-tcp DBusServer runs out of memory (fd.o #107194, Simon McVittie)
• Don't use misleading errno-derived error names if getaddrinfo() or getnameinfo() fails with a code other than EAI_SYSTEM (fd.o #106395, Simon McVittie)
• Skip tests that require working TCP if we are in a container environment where 127.0.0.1 cannot be resolved (fd.o #106812, Simon McVittie)
