A memory allocation failure happening during peers_register_table would
have resulted in a crash. This function is only called during init.
It was raised in GitHub issue #1233.
It could be backported to all stable branches.
This one was not easy because it was embarking many includes with it,
which other files would automatically find. At least global.h, arg.h
and tools.h were identified. 93 total locations were identified, 8
additional includes had to be added.
In the rare files where it was possible to finalize the sorting of
includes by adjusting only one or two extra lines, it was done. But
all files would need to be rechecked and cleaned up now.
It was the last set of files in types/ and proto/ and these directories
must not be reused anymore.
This one is particularly difficult to split because it provides all the
functions used to manipulate a proxy state and to retrieve names or IDs
for error reporting, and as such, it was included in 73 files (down to
68 after cleanup). It would deserve a small cleanup though the cut points
are not obvious at the moment given the number of structs involved in
the struct proxy itself.
The stktable_types[] array declaration was moved to the main file as
it had nothing to do in the types. A few declarations were reordered
in the types file so that defines were before the structs. Thread-t
was added since there are a few __decl_thread(). The loss of peers.h
revealed that cfgparse-listen needed it.
The cfg_peers external declaration was moved to the main file instead
of the type one. A few types were still missing from the proto, causing
warnings in the functions prototypes (proxy, stick_table).
