3eb43c6ef5 Moved DoubleLoadStorageHandler to end of functions, improve fast path l8ui performance 
This allows a conditional branch that previously required a full jump instruction not to require it.

e4c76b488c Remove the unaligned load handler to its own source file as it was getting quite complex 
The downside here is needing to use #include so the 'beq' in the
exception vector can land on it directly, save an instruction.

There might be a better way to do this, but it seems hard to "curate"
the order that symbols appear in each section.

f585ed8f46 Rename GPIO_CONF_PUSH_PULL to GPIO_CONF_OPEN_DRAIN 
Seems I got the functionality of this bit inverted when
initially testing.

In testing it also seems open drain mode is ignored on some pins, which
still source current. Needs more investigation though (may be pullups
internal to the ESP modules or set by default in software.)

Relates to #45

1221e2117b Rework component makefiles to have a default <component>_ROOT 
This fixes a long-standing bug where build directories sometimes
expanded many levels deeper than they should have.

Component names can now no longer contains slashes (ie the component
name for 'extras/i2c' is now just 'i2c')

c19bb63286 Reorder library arguments so component libraries come first 
This allows components to override weak linked symbols in the core or
the SDK libraries, without needing to force symbol discovery.

Will help with #24, for instance.

1eb0e58997 Use fixed symbol rename list 
To keep things from changing out from under us as we slowly replace bits of the
SDK libs, changing Makefiles to not auto-generate the list of symbols to
rename, but always use the same list every time.
