Dan Elphick 7f5383e8ad [base] Move utils/vector.h to base/vector.h
The adding of base:: was mostly prepared using git grep and sed:
git grep -l <pattern> | grep -v base/vector.h | \
  xargs sed -i 's/\b<pattern>\b/base::<pattern>/
with lots of manual clean-ups due to the resulting
v8::internal::base::Vectors.

#includes were fixed using:
git grep -l "src/utils/vector.h" | \
  axargs sed -i 's!src/utils/vector.h!src/base/vector.h!'
