MFH r190382,190416,190525:

- getaddrinfo(3) should accept numeric when ai_socktype is not
  specified in hint or hints is NULL.
- Add support for SCTP to getaddrinfo(3).
  Now, getaddrinfo(3) returns two SOCK_STREAMs, IPPROTO_TCP and
  IPPROTO_SCTP.  It confuses some programs.  If getaddrinfo(3) returns
  IPPROTO_SCTP when SOCK_STREAM is specified by hints.ai_socktype, at
  least Apache doesn't work.  So, I made getaddrinfo(3) to return
  IPPROTO_SCTP with SOCK_STREAM only when IPPROTO_SCTP is specified
  explicitly by hints.ai_protocol.
- Query DNS only once per an address family.

7.2 will be the first release where strndup() appears.

Approved by:	re (kensmith)

Mostly synchronize lib/libthr and sys/kern/kern_umtx.c with the code

2009-03-24T20:57:10+00:00

from HEAD.

Since libkse is still built on RELENG_7, pthread_cleanup_push/pop
are left as the functions, but the support code in libthr is present for
the macro versions.

Malloc in RELENG_7 does not require thread exit hook, but I decided
to add empty handler for it, instead of removing callback from thr_exit().

No mergeinfo since this change is prepared by patching libthr and then
bringing in required missed bits.

MFC r189283:

2009-03-12T13:45:55+00:00

Correct types of variables used to track amount of allocated SysV shared memory from int to size_t. Implement a workaround for current ABI not allowing to properly save size for and report more then 2GB sized segment of shared memory. This makes it possible to use > 2 GB shared memory segments on 64bit architectures. Please note the new BUGS section in shmctl(2) and UPDATING note for limitations of this temporal solution. MFC r189398: Systematically use vm_size_t to specify the size of the segment for VM KPI. Do not overload the local variable size in kern_shmat() due to vm_size_t change. Fix style bug by adding explicit comparision with 0. MFC r189399: Improve the grammar and wording in the changes to shmctl(2) manpage. Put an UPDATING entry and bump __FreeBSD_version for the change.
