PR/51578: Henning Petersen: Fix leak on error.

KNF, no real change (except malloc(x * y) -> calloc(x, y))

branches: 1.22.2;
make more descriptors that we open as close-on-exec

Replace previous Sun Microsystems, Inc. license with a standard
BSD 3-clause license granted by Oracle America, Inc..
This license change was approved by Wim Coekaerts, Senior Vice President,
Linux and Virtualization at Oracle Corporation.

This fixes PR lib/45293 by Pedro Giffuni.

branches: 1.20.2;
Use C89 definitions
Remove use of __P

branches: 1.19.2; 1.19.4;
close on exec fixes:
- open + fcntl -> open O_CLOEXEC
- configuration database file descriptors that can stay open are now opened
fopen(db, "re")

Use __isthreaded from reentrant.h and don't redeclare it.

branches: 1.17.8;
- always check malloc results
- don't leak fds on error
- don't cast malloc
- don't cast NULL

branches: 1.16.10;
Remove more duplicate #includes, and a few spurious whitespaces at EOL
From Slava Semushin <slava.semushin@gmail.com>

Coverity CID 2275: Avoid memory leak on error.

WARNS=4

Make the arg to getnetconfigent const char * to match the man page (and
likely calling code).

__RCSID police

The second parameter of strchr() is an integer, not a pointer.
So use '\0' instead of NULL.

Merge the nathanw_sa branch.

Fix signed/unsigned comparison warnings.

* Adapt include files for rpc_com.h/rpc_internal.h split.
* Add rpc_control to svc.c
* Implement non-blocking connections.

branches: 1.7.2;
Various typos in comments (neccessary, sceme, choise, ...).

branches: 1.6.2;
make local constant arrays const

whitespace consistency fixups

sprinkle _DIAGASSERT() appropriately. minor other cleanups

add __RPC_GETXID macro
don't const castway __rpc_getconf and __rpc_getconfig. It might try to
write const strings
fix non-portable casts
remove duplicated prototypes
cast things to proper types
remove extraneous casts to NULL
fix variable cast mismatches
remove register var declarations

PR/10499: IWAMOTO Toshihiro: getnetconfig uses strtok. Applied suggested patch
to use strtok_r

branches: 1.1.2; 1.1.4;
Add new RPC code, based on Sun's TI-RPC code. Adapted to not use XTI,
but sockets instead, internally. Old, backward compatible interfaces
maintained.
