Stop using -no-cpp-precomp on Darwin or OS X. The Apple-modified gcc …
8652cc9 
…hasn't

needed it in over a decade, and GNU gcc spews warnings about it.

Misty De Meo provided the best research:

    The last release I can find where -cpp-precomp did anything is 2.95.2 
    (Apple build 937.2), from the December 2002 Xcode, prior to the release
    of Xcode 1.0 (presumably the one that shipped with it): 
    http://opensource.apple.com/source/gcc/gcc-1640/gcc/gcc.c

    In subsequent releases -cpp-precomp and -no-cpp-precomp were both made
    no-ops. The last time they were mentioned was in the install.texi from
    Apple GCC build 1765, from the WWDC 2004 developer tools; it was already
    a no-op by then.

@ylavic
Introduce apr_skiplist_last[_compare]() and apr_skiplist_remove_node().
b295a7a 
The apr_skiplist_last[_compare]() functions return the last matching element
(duplicate) whereas the existing apr_skiplist_find[_compare]() return the first
one encountered during the walk.

The function apr_skiplist_remove_node() function allows to remove an element
given its node, e.g. an iterator from apr_skiplist_{getlist,previous,next}().

The goal is to have a reliable way to find (and remove) any element having a
unique address/pointer, by starting with the last duplicate and then iterating
on the previous ones until the match (see example in testskiplist.c).

apr_skiplist_last() is much more efficient than apr_skiplist_first() would be,

skiplist: fix the minimum height (to one).
f0f6e32 
The height of a skiplist is always at least one, for the top node,
even if our implementation may delay its creation on the first insert
or delete it on the last remove.
This also helps apr_skiplist_remove() to never return zero (not found)
when it deletes the last node.

SECURITY: CVE-2015-1829 (cve.mitre.org)
61dde58 
APR applications using APR named pipe support on Windows can be 
vulnerable to a pipe squatting attack from a local process; the extent
of the vulnerability, when present, depends on the application.
Initial analysis and report was provided by John Hernandez of Casaba 
Security via HP SSRT Security Alert.

The above commits added the checks for HAVE_GETRANDOM and HAVE_ARC4RANDOM first
in configure.in so to avoid breaking the AC_MESSAGE_CHECKING/RESULT line, thus
it also defined the macros unconditionally (while the others were and still are
only defined if no previous one is elected already).

Yet the top priority one should remain HAVE_EGD when --with-egd is specified,
so we now have to rearrange apr_generate_random_bytes()'s #ifdefs to preserve
that now.

While at it, let's add an #error for the "should not happen" case where
APR_HAS_RANDOM is defined but no implementation is found.

Note discussion on dev@apr.apache.org. Because this introduces a new dependency for maintainers
using buildconf to obtain autoconf-archive, the group may choose to reject the proposal and revert.
To be determined.

This is from a vpath build.
