Merge of r4778, r4782, r4783, r4824, r4830, r4834: minor fixes.
*) Reorder checks in ngx_shared_memory_add() for more consistent
error messages.
*) Added "const" to ngx_memcpy() with NGX_MEMCPY_LIMIT defined. This
fixes warning produced during compilation of the ngx_http_geoip_module
due to const qualifier being discarded.
*) Fixed possible use of old cached times if runtime went backwards.
If ngx_time_sigsafe_update() updated only ngx_cached_err_log_time, and
then clock was adjusted backwards, the cached_time[slot].sec might
accidentally match current seconds on next ngx_time_update() call,
resulting in various cached times not being updated.
Fix is to clear the cached_time[slot].sec to explicitly mark cached times
are stale and need updating.
*) Radix tree preallocation fix. The preallocation size was calculated
incorrectly and was always 8 due to sizeof(ngx_radix_tree_t) accidentally
used instead of sizeof(ngx_radix_node_t).
*) Fixed overflow if ngx_slab_alloc() is called with very big "size"
argument.
*) Write filter: replaced unneeded loop with one to free chains.
