Converted condition variable docs to mdbook.

This also is implemented using a single unified manual page
that should be easier to reference.

-== NAME
-
-nng_cv_until - wait for condition or timeout
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-
-int nng_cv_until(nng_cv *cv, nng_time when);
-----
-
-== DESCRIPTION
-
-The `nng_cv_until()` waits until either the condition variable _cv_ is signaled
-by another thread calling either xref:nng_cv_wake.3supp.adoc[`nng_cv_wake()`] or
-xref:nng_cv_wake1.3supp.adoc[`nng_cv_wake1()`], or the system clock (as tracked
-by xref:nng_clock.3supp.adoc[`nng_clock()`]) reaches _when_.
-
-The caller must have have ownership of the mutex that was used when
-_cv_ was allocated.
-This function will drop the ownership of that mutex, and reacquire it
-atomically just before returning to the caller.
-(The waiting is done without holding the mutex.)
-
-NOTE: Any condition may be used or checked, but the condition must be
-checked, as it is possible for this function to wake up spuriously.
-The best way to do this is inside a loop that repeats until the condition
-tests for true.
-
-== EXAMPLE
-
-The following example demonstrates use of this function:
-
-.Example 1: Waiting for the condition
-[source, c]
-----
-
-    expire = nng_clock() + 1000; // 1 second in the future
-    nng_mtx_lock(m);  // assume cv was allocated using m
-    while (!condition_true) {
-        if (nng_cv_until(cv, expire) == NNG_ETIMEDOUT) {
-            printf("Time out reached!\n");
-            break;
-        }
-    }
-    // condition_true is true
-    nng_mtx_unlock(m);
-----
-
-.Example 2: Signaling the condition
-[source, c]
-----
-    nng_mtx_lock(m);
-    condition_true = true;
-    nng_cv_wake(cv);
-    nng_mtx_unlock(m);
-----
-
-== RETURN VALUES
