Adjust for new NaCl startup ABI

Adjust for new NaCl startup ABI

This replaces the startup code for applications (crt1.o) and the dynamic
linker startup and glue code with versions adapted to the new NaCl startup
ABI.  This uses the normal C function-call ABI to start the e_entry address
as a function of one argument, that being an information block holding the
arguments, environment, etc.

This is to enable http://codereview.chromium.org/7276050/, which see.

Roland,

I'm looking into this.

My kind request would be to provide a document on NaCl startup ABI. From the
review you linked with this one it is somewhat clear what you are doing, but the
public document that describes this part of ABI is needed anyway.

You can add something to this collection (pretty tiny yet)):

lgtm

Please keep an eye on this and on the related TCB change until all the bots go
back green.

Please don't procrastinate writing a doc :-)

to keep it sorted overall).
