arturo182 021df5d3d3 nrf: Cleanup AnalogOut and throw an exception in constructor
The nRF MCUs do not support analog output. Throwing an exception
in the constructor will stop users from creating an instance of
the AnalogOut class.

In the future we can ifdef-out the whole class so it is not available
in the module at all.

Scott Shawcroft dff744558b Make parsing more memory flexible.
The parser attempts to allocate two large (~512 byte) chunks up
front. If it couldn't, then it would error out. This change will
cause it to try allocating half the previous attempt until its down
to two copies. This is ok upfront because later code checks bounds
and tries to extend the allocation if needed.

Scott Shawcroft da330f0cab Polish up the heap analysis script and make it more CLI friendly.
It can now render the heap layout over a sequence of ram dumps.

The mpy analysis is also better at parsing mpy files.

Scott Shawcroft 416abe33ed Introduce a long lived section of the heap.
This adapts the allocation process to start from either end of the heap
when searching for free space. The default behavior is identical to the
existing behavior where it starts with the lowest block and looks higher.
Now it can also look from the highest block and lower depending on the
long_lived parameter to gc_alloc. As the heap fills, the two sections may
overlap. When they overlap, a collect may be triggered in order to keep
the long lived section compact. However, free space is always eligable
for each type of allocation.

By starting from either of the end of the heap we have ability to separate
short lived objects from long lived ones. This separation reduces heap
fragmentation because long lived objects are easy to densely pack.

Most objects are short lived initially but may be made long lived when
they are referenced by a type or module. This involves copying the
memory and then letting the collect phase free the old portion.

QSTR pools and chunks are always long lived because they are never freed.

The reallocation, collection and free processes are largely unchanged. They
simply also maintain an index to the highest free block as well as the lowest.
These indices are used to speed up the allocation search until the next collect.

In practice, this change may slightly slow down import statements with the
benefit that memory is much less fragmented afterwards. For example, a test
import into a 20k heap that leaves ~6k free previously had the largest
continuous free space of ~400 bytes. After this change, the largest continuous
free space is over 3400 bytes.

Scott Shawcroft 56bd0789af Speed up qstr loading by using the stack to store a temporary

Scott Shawcroft 6560596864 Switch to m_malloc_maybe and m_free to reduce our dependence on gc_alloc.
gc_alloc's API is changing and we shouldn't need to care about it.
So, we switch to m_malloc which has the default behavior we expect.
