+
+ handle loss of syslog socket connection
+
+ when traditional syslogd implementations are restarted, the old server
+ socket ceases to exist and a new unix socket with the same pathname is
+ created. when this happens, the default destination address associated
+ with the client socket via connect is no longer valid, and attempts to
+ send produce errors. this happens despite the socket being datagram
+ type, and is in contrast to the behavior that would be seen with an IP
+ datagram (UDP) socket.
+
+ in order to avoid a situation where the application is unable to send
+ further syslog messages without calling closelog, this patch makes
+ syslog attempt to reconnect the socket when send returns an error
+ indicating a lost connection.
+
+ additionally, initial failure to connect the socket no longer results
+ in the socket being closed. this ensures that an application which
+ calls openlog to reserve the socket file descriptor will not run into
+ a situation where transient connection failure (e.g. due to syslogd
+ restart) prevents fd reservation. however, applications which may be
+ unable to connect the socket later (e.g. due to chroot, restricted
+ permissions, seccomp, etc.) will still fail to log if the syslog
+ socket cannot be connected at openlog time or if it has to be
+ reconnected later.

+
+ add musl-clang, a wrapper for system clang installs
+
+ musl-clang allows the user to compile musl-powered programs using their
+ already existent clang install, without the need of a special cross compiler.
+ it achieves this by wrapping around both the system clang install and the
+ linker and passing them special flags to re-target musl at runtime.
+ it does only affect invocations done through the special musl-clang wrapper
+ script, so that the user setup remains fully intact otherwise.
+
+ the clang wrapper consists of the compiler frontend wrapper script,
+ musl-clang, and the linker wrapper script, ld.musl-clang.
+ musl-clang makes sure clang invokes ld.musl-clang to link objects; neither
+ script needs to be in PATH for the wrapper to work.

+
+ build: fix musl-targeting toolchain test
+
+ the old test was broken in that it would never fail on a toolchains built
+ without dynamic linking support, leading to the wrapper script possibly being
+ installed on compilers that do not support it. in addition, the new test is
+ portable across compilers: the old test only worked on GCC.
+
+ the new test works by testing whether the toolchain libc defines __GLIBC__:
+ most non-musl Linux libc's do define this for compatibility even when they
+ are not glibc, so this is a safe bet to check for musl. in addition, the
+ compiler runtime would need to have a somewhat glibc-compatible ABI in the
+ first place, so any non-glibc compatible libc's compiler runtime might not
+ work. it is safer to disable these cases by default and have the user enable
+ the wrappers manually there using --enable-wrapper if they certain it works.

+
+ build: overhaul wrapper script system for multiple wrapper support
+
+ this overhauls part of the build system in order to support multiple
+ toolchain wrapper scripts, as opposed to solely the musl-gcc wrapper as
+ before. it thereby replaces --enable-gcc-wrapper with --enable-wrapper=...,
+ which has the options 'auto' (the default, detect whether to use wrappers),
+ 'all' (build and install all wrappers), 'no' (don't build any) and finally
+ the options named after the individual compiler scripts (currently only
+ 'gcc' is available) to build and install only that wrapper.
+ the old --enable-gcc-wrapper is removed from --help, but still available.
+
+ it also modifies the wrappers to use the C compiler specified to the build
+ system as 'inner' compiler, when applicable. as wrapper detection works by
+ probing this compiler, it may not work with any other.

+ dynlink.c: pass gnu-hash table pointer to gnu_lookup
+
+ The callers need to check the value of the pointer anyway, so make
+ them pass the pointer to gnu_lookup instead of reloading it there.
+
+ Reorder gnu_lookup arguments so that always-used ones are listed
+ first. GCC can choose a calling convention with arguments in registers
+ (e.g. up to 3 arguments in eax, ecx, edx on x86), but cannot reorder
+ the arguments for static functions.

+ dynlink.c: use bloom filter in gnu hash lookup
+
+ Introduce gnu_lookup_filtered and use it to speed up symbol lookups in
+ find_sym (do_dlsym is left as is, based on an expectation that

+ RTLD_NEXT or RTLD_DEFAULT, and will not need to look at more than one
+ DSO).
