Summary:
This completly changes the way modal numinput is handled. Now, edited expression is a string, which then gets unit- and py-evaluated to get a float value.
We gain many power and flexibility, but lose a few "shortcuts" like '-' to negate, or '/' to inverse (if they are really needed, we still can add them with modifiers, like e.g. ctrl-/ or so).
Features:
- units (cm, ", deg, etc.).
- basic operations from python/BKE_unit (+, *, **, etc.), and math constants and functions (pi, sin, etc.).
- you can navigate in edited value (left/right key, ctrl to move by block) and insert/delete chars, e.g. to fix a typo without having to rewrite everything.
- you can go to next/previous value with (ctrl-)TAB key.
- As before, hitting backspace after having deleted all leading chars will first reset the edited value to init state, and on second press, the whole "modal numinput" editing will be cancelled, going back to usual transform with mouse.
Notes:
- Did not touch to how values are shown in header when modal numinput is not enabled (would do that in another commit), so this is still quite inconsistent.
- Added back radian support in BKE_unit.
- Added arcminute/arcsecond to BKE_unit.
(those unit changes affect all angle UI controls, btw, so you can now enter radians or longitude/latitude values when in degrees units).

Thanks everybody!
Differential Revision: http://developer.blender.org/D61
Issue was actually that micrometer was not drawing correctly (from r58165), reverted that fix and instead use utf8 drawing for editmode metrics when using a unit system (we already had a similar hack for surfaces and volumes, anyway).
I've added a separate camera unit type. It's a bit strange to have an exception for
this but it ensures units are shown in familiar millimeters and it also ensures
backwards compatibility.
Initially problem was caused by updated version of mingw-runtime which
changed behavior of snprintf and vsnprintf so %lf isn't anymore valid
for doubles.
According to manpages, %f is a correct format for snprintf for doubles.
* replace by BLI_snprintf in various places, note _snprintf on windows
does not properly null terminate the string.
* fix overflow in sequencer proxy code due to buffer being smaller than
specified size.
* fix some usage of snprintf as strcpy, this is will go wrong if the
string contains % characters.
* remove BLI_dynstr_printf function in gpu module, use BLI_dynstr_appendf
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
[#25159] Vertex locations dont read correctly and are not labeled correctly in the properties bar.
- non rna buttons can now have units set.
- calls with invalid units system now raises an assert().
- include .mxf in filter.
