When the gdbpy_ref objects get destroyed, they call Py_DECREF to
decrement the reference counter of the python object they hold a
reference to. Any time we call into the Python API, we should be
holding the GIL. The gdbpy_enter object does that for us in an
RAII-fashion.
However, if gdbpy_enter is declared after a gdbpy_ref object in a
function, gdbpy_enter's destructor will be called (and the GIL will be
released) before gdbpy_ref's destructor is called. Therefore, we will
end up calling Py_DECREF without holding the GIL.
This became obvious with Python 3.6, where memory management functions
have asserts to make sure that the GIL is held. This was exposed by
tests py-as-string.exp, py-function.exp and py-xmethods. For example:
(gdb) p $_as_string(enum_valid)

New in v2:
- Define PyMem_RawMalloc as PyMem_Malloc for Python < 3.4 and use
PyMem_RawMalloc in the code.
Since Python 3.4, the callback installed in PyOS_ReadlineFunctionPointer
should return a value allocated with PyMem_RawMalloc instead of
PyMem_Malloc. The reason is that PyMem_Malloc must be called with the
Python Global Interpreter Lock (GIL) held, which is not the case in the
context where this function is called. PyMem_RawMalloc was introduced
for cases like this.
In Python 3.6, it looks like they added an assert to verify that
PyMem_Malloc was not called without the GIL. The consequence is that
typing anything in the python-interactive mode of gdb crashes the
process. The same behavior was observed with the official package on
Arch Linux as well as with a manual Python build on Ubuntu 14.04.
This is what is shown with a debug build of Python 3.6 (the error with a
non-debug build is far less clear):

Years ago we contributed flash programming patches upstream. The following
patch is a leftover one that complements that functionality by adding a new
command to erase all reported flash memory blocks.
The command is most useful when we're dealing with flash-enabled targets
(mostly bare-metal) and we need to reset the board for some reason.
The wiping out of flash memory regions should help the target come up with a
known clean state from which the user can load a new image and resume
debugging. It is convenient enough to do this from the debugger, and there is
also an MI command to expose this functionality to the IDE's.

When displaying the section headers table using objdump (-h), the column
containing the section header name is currently fixed at 13 characters.
A section name that is longer than 13 characters will overflow the
column causing the table to become miss-aligned.
In this commit I change the behaviour so that _in wide mode_ (-w -h) the
section name column is dynamically resized to fit the longest section
name we plan to display. In wide mode the column still retains a
minimum width of 13 characters.
In non-wide more the behaviour is completely unchanged.
While I was changing the dump_headers function I have unified the two
printf lines that handled the different address widths into a single
printf, the address width is now passed into printf using the '*' field
width format character.

Fix a generic ELF linker regression introduced with a chain of changes
made to unused input section garbage collection:
- commit 1a766c6843 ("Also hide symbols without PLT nor GOT
references."),
<https://sourceware.org/ml/binutils/2011-09/msg00076.html>,
- commit 1d5316ab67 ("PR ld/13177: garbage collector retains zombie
references to external libraries"),
<https://sourceware.org/ml/binutils/2011-10/msg00161.html>,
- commit 6673f753c0 ("Fix PR 12772, garbage collection of dynamic
syms"), <https://sourceware.org/ml/binutils/2011-12/msg00077.html>,
causing the garbage collection of unused symbols present in a DSO
involved in a link to make identically named symbols ordinarily defined
(i.e. not hidden or PROVIDEd) by a linker script local, even though the
latter symbols are supposed to be global as if no DSO defined them as
well.
This is because linker script assignments are processed very late as
`lang_process' proceeds, down in the call to `ldemul_before_allocation',
which is made after the call to `lang_gc_sections' to do input section
garbage collecting. Consequently if unused, then any such DSO-defined
symbol has already been garbage-collected and internally marked local.
It would ordinarily be removed from dynamic symbol table output, however
a linker script assignment correctly replaces its original definition
with the new one and enters it into the dynamic symbol table produced as
it is supposed to be exported. The original local marking is however
retained making the symbol local in the dynamic symbol table and
therefore not available externally. This also causes a sorting problem
with the MIPS target, which does not expect non-section local dynamic
symbols to be output and produces an invalid binary.
Fix the problem then, by removing the `forced_local' marking for the
offending case and add suitable test cases. First to verify that unused
symbols ordinarily defined with linker script assignments remain
exported in the context of input section garbage collection whether or
not a DSO defining identically named symbols is present in the link.
Second that a linker version script still correctly retains or removes
such symbols as requested.

Correct a regression from commit 8614eeee67 ("Traditional MIPS
patches"), <https://sourceware.org/ml/binutils/2000-07/msg00018.html>,
which caused symbols in linkonce or what is these days known as comdat
sections to be treated as external for the purpose of PIC relocation
generation even if their binding remains STB_LOCAL. This in turn
disabled GOT16/LO16 relocation pairing with references to such symbols,
as no complementing LO16 relocation is expected for external GOT16
references in the o32 ABI, which ultimately leads to link errors, e.g.:
ld: comdat-reloc.o: Can't find matching LO16 reloc against `foo' for R_MIPS_GOT16 at 0x24 in section `.text.bar[bar]'
as with the LD test case included with this change.
