d08d1cbd67 Linkgraph: Avoid attempting to merge/apply job when cleaning schedule. 
This can cause crashes when switching savegame.
Move job merge/apply out of destructor into separate function.

84e61b690a Linkgraph: Changes to job scheduling algorithm. 
This is to improve responsiveness of link graph updates, whilst
avoiding being blocked waiting for updates to complete.
Previously, large numbers of cheap jobs resulted in poor responsiveness
as it took a long time for jobs to cycle round.

Add 'linkgraph' debug category.

61ff4f5d97 Limit linkgraph recalc interval to minimum of 2 ticks. 
The interval could otherwise fall to 1 tick at very high day lengths,
and low number of days interval, with recalc not scaled by day length
enabled.

78cf5ca682 Add setting for linkgraph times to be in non daylength scaled days. 
Savegame format change for link graph jobs.
Change link graph scheduler to support more than one operation
per day, on _date_fract ticks other than SPAWN_JOIN_TICK.

3896952136 Join more than one link graph job at once where possible. 
This can occur when the link graph recalculation times are changed.
In particular, if the duration or interval are reduced, the new jobs
will be delayed until the completion of the previous long job,
and then remain backlogged thereafter as jobs are dequeued at the same
rate as they are queued.

58b6bf16c3 Linkgraph: Enable MCF custom allocator only for GCC 4.9+

e22e1df939 Store annotation and node ID in set key, to reduce ptr derefs on sort. 
Store the set iterator in the node, for faster erasing during forks.

Use a custom pool allocator to store set nodes contiguously.

0fb79a8f15 Use a flat vector instead of a map in FlowEdgeIterator. 
This reduced the cost of Dijkstra<CapacityAnnotation> by approx. 25%,
in a test profiling.

564744d427 Cache the calculated value of CapacityAnnotation. 
This is because CapacityAnnotation::Comparator::operator()
was appearing at the top of profiler output due to regenerating
the annotation value on every comparison when performing a set operation.

c6854afcef Pause the game instead of blocking when link graph jobs lag. 
Check if the job is still running one date fract tick before it
is due to join and if so pause the game until its done.
This avoids the main thread being blocked on a thread join.
Show if pause is due to link graph job in status bar, update network
messages.
This does not apply for network clients.
