410614d6b3 Replace _FPOS_OVERFLOW() macro with a static inline function called 
__fpos_overflow() that doesn't cause any lint warnings.

4c968434a3 Make setenv(3) follow the standard, by rejecting invalid strings. It 
now fails with EINVAL errno when variable is NULL, empty or contains
an `=' character; or value is NULL.

Adjust the man page accordingly, and exercize them in the existing
environment testcase.

4a94dc0b8f Avoid unnecessary malloc(). Since __findenv() kindly treats 
equal sign as an end of string, we can pass the string of
form "key=value" to lookup "key".

ae557324e5 Restore binary compatibility with applications which use putenv(3) 
on constant strings (e.g. postdrop(1)):
- Don't write to the environment string passed to putenv(3).
- Don't overwrite the value of an existing environment string
  unless the memory was actually allocated by setenv(3).

2445ce72d2 Be slightly more careful about freeing memory allocated for environment 
variables: only free memory if the current value points to the same
memory area as the allocated block. This will prevent crashes if an
application changes the order of the environment array.

Unfortunately this is still not enough to stop zsh 4.2.* from crashing.
zsh 4.3.* works fine before and after this change.

5cdca2e600 Remember memory used by allocated environment variables instead of 
using a bitmap. This deals with the case where a variable is first
set via setenv(3) or putenv(3), then overwritten by changing
"environ" directory and afterwards overwritten with setenv(3) again.

This stops "zsh" from crashing under NetBSD-current.

Code reviewed by Christos Zoulas.

e957123b85 PR/43899: Nicolas Joly: setenv(3)/unsetenv(3) memory leak. 
Partial fix: Don't allocate a new string if the length is equal to the
old length, because presumably the old string was also nul terminated
so it has the extra byte needed.
The real fix is to keep an adjunct array of bits, one for each environment
variable and keep track if the entry was allocated or not so that we can
free it in unsetenv.

2a4732aadc Only do the __libc_init hack in libc, i.e. remove it from ld.elf_so. 
This fixes hppa ld.elf_so by reducing the number of PLABELs required to
