   XXX LEAKTEST doesn't really work in perl5.  There are direct calls to
   safemalloc() in the source, so LEAKTEST won't pick them up.
   (The main "offenders" are extensions.)
   Further, if you try LEAKTEST, you'll also end up calling
   Safefree, which might call safexfree() on some things that weren't
   malloced with safexmalloc.  The correct "fix" to this, if anyone
   is interested, is to ensure that all calls go through the New and
   Renew macros.

/*
=for apidoc Am|SV*|NEWSV|int id|STRLEN len
Creates a new SV.  A non-zero C<len> parameter indicates the number of
bytes of preallocated string space the SV should have.  An extra byte for a
tailing NUL is also reserved.  (SvPOK is not set for the SV even if string
space is allocated.)  The reference count for the new SV is set to 1.
C<id> is an integer id between 0 and 1299 (used to identify leaks).

=for apidoc Am|void|New|int id|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<malloc> function.

=for apidoc Am|void|Newc|int id|void* ptr|int nitems|type|cast
The XSUB-writer's interface to the C C<malloc> function, with
cast.

=for apidoc Am|void|Newz|int id|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<malloc> function.  The allocated
memory is zeroed with C<memzero>.

=for apidoc Am|void|Renew|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<realloc> function.

=for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
The XSUB-writer's interface to the C C<realloc> function, with
cast.

=for apidoc Am|void|Safefree|void* ptr
The XSUB-writer's interface to the C C<free> function.

=for apidoc Am|void|Move|void* src|void* dest|int nitems|type
The XSUB-writer's interface to the C C<memmove> function.  The C<src> is the
source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
the type.  Can do overlapping moves.  See also C<Copy>.

=for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
The XSUB-writer's interface to the C C<memcpy> function.  The C<src> is the
source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
the type.  May fail on overlapping copies.  See also C<Move>.

=for apidoc Am|void|Zero|void* dest|int nitems|type

The XSUB-writer's interface to the C C<memzero> function.  The C<dest> is the
destination, C<nitems> is the number of items, and C<type> is the type.

=for apidoc Am|void|StructCopy|type src|type dest|type
This is an architecture-independent macro to copy one structure to another.
