clang complains on x86 when building main.c:116:2: error: embedding a #include directive within macro arguments is not supported ^ convert nesting include into a string assignment, to same effect but making it compatible with clang as well Signed-off-by: Khem Raj <raj.khem@gmail.com>

A frequent cause of crashes on shutdown happens when the quit signal has been received and the main thread and other threads race each other at shutdown. As in the typical stack trace below what happens is that the main thread unloads the plugins while they are still being used by one of the connection threads, causing the connection thread to segfault after calling dlclosed functions. To avoid this simply count the number of connection threads we create, and at exit in the main thread wait until this count drops to 0 before we actually start unloading anything.

The zstd allocator crashed when asked to either fill or zero space
that had previously been unallocated. This adds a check for this
case.
