1631a78097 Allow storing and receiving the LWP private pointer via ucontext_t 
on all platforms except VAX and IA64. Add fast access via register for
AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace
the stack based pthread_self(). Implement skeleton support for Alpha,
HPPA, PowerPC, SPARC and SPARC64, but leave it disabled.

Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in
machine/types.h and a corresponding __lwp_getprivate_fast in
machine/mcontext.h.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

9674b81ed9 Introduce __weakref_visible to handle the different required visibility 
for weak references. GCC 4.2+ and Clang require static, older GCC wants
extern. Change __weak_reference to include sym. This requires changes
the existing users to not reuse the name of the symbol, but avoids
further differences between GCC 4.1 and GCC 4.2+/clang.

This works by having the inline wrapper calling a second function which

5f7e80a834 Add support for the Extensible MIPS ("eMIPS") platform. The 
NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the
Giano system simulator.

eMIPS is a platform developed at Microsoft Research for researching
reconfigurable computing.  eMIPS allows dynamic loading and scheduling
of application-specific circuits for the purpose of accelerating
computations based on the current workload.

NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research
by Alessandro Forin and Neil Pittman.  Microsoft Corporation has
donated full copyright to The NetBSD Foundation.

Platform support for eMIPS is the first part of Microsoft's
contribution.  The second part includes the hardware accelerator
framework and will be proposed on tech-kern soon.

d0e6f50de3 Implement mark & sweep garbage collection as suggested by Enami Tsugutomo 
on "current-users" mailing list. Garbage collection is performed if:
1.) We previously allocated memory for the environment array which

2.) We find a non-NULL pointer in the allocated environment array after
    the end of the environment. This happens if the applications attempts
    to clear the environment with something like "environ[0] = NULL;".

2.) Add a wrapper function __findenv() which implements the previous
    *internal* interface. It turns out that ld.elf_so(1) and pthread(3)
    both use it.

Stripping e.g. "LD_LIBRARY_PATH" from the environment while running
setuid binaries works again now.

fbf4aa1699 Improve and simplify implementation of *env(3) functions: 
- Use RB tree to keep track of memory allocated via setenv(3) as
  suggested by Enami Tsugutomo in private e-mail.
  This simplifies the code a lot as we no longer need to keep the size
  of "environ" in sync with an array of allocated environment variables.
  It also makes it possible to free environment variables in unsetenv(3)
  if something has changed the order of the "environ" array.
- Fix a bug in getenv(3) and getenv_r(3) which would return bogus
  results e.g. for " getenv("A=B") " if an environment variable "A"
  with value "B=C" exists.
- Clean up the internal functions:
  - Don't expose the read/write lock for the environment to other parts
    of "libc". Provide locking functions instead.
  - Use "bool" to report success or failure.
  - Use "ssize_t" or "size_t" instead of "int" for indexes.
  - Provide internal functions with simpler interfaces e.g. don't
    combine return values and reference arguments.
  - Don't copy "environ" into an allocated block unless we really need
    to grow it.

Code reviewed by Joerg Sonnenberger and Christos Zoulas, tested by
Joerg Sonnenberger and me. These changes also fix problems in
zsh 4.3.* and pam_ssh according to Joerg.
