Introduce a gdb_ref_ptr specialization for struct value
struct value is internally reference counted and so, while it also has
some ownership rules unique to it, it makes sense to use a gdb_ref_ptr
when managing it automatically.
This patch removes the existing unique_ptr specialization in favor of
a reference-counted pointer. It also introduces two other
clarifications:
1. Rename value_free to value_decref, which I think is more in line
with what the function actually does; and
2. Change release_value to return a gdb_ref_ptr. This change allows
us to remove the confusing release_value_or_incref function,
primarily by making it much simpler to reason about the result of
release_value.

MIPS: Fix GOT page counter in multi-got links
The record_got_page_entry function records and updates the maximum
number of GOT page entries which may be required by an object. In the
case where an existing GOT page entry was expanded, only the entry
belonging to output GOT would have its page count updated. This leaves
the entry belonging to the object GOT with the num_pages count of 1 it
was originally initialized with. Later on when GOTs are being merged in a
multi-got link, this causes the value of entry->num_pages in
add_got_page_entries to always be 1 and underestimates the number of pages
required for the new entry. This in turn leads to an assertion failure in
get_got_page_offset where we run out of pages.
Fix by obtaining the object's GOT entry unconditionally and not just
the first time it gets created. Now that entry2 is always valid, remove
the useless NULL checks.

binutils/testsuite: Support REL and MIPS64 reloc formats with `strip-13'
Add source variants for the `strip-13' test that produce relocations in
the REL and MIPS64 formats, fixing a failure for the `mips64el-openbsd'
target. This also corrects output for `i*86-*', `i960-*', `m6812-*' and
`m68hc12-*', o32 `mips*-*', and `score*-*' targets, which however does
not show up as a test result change due to lax error message matching
causing `bad value' previously produced by `strip' as a result of input
file rejection to be accepted as a test pass.
For `m6811-*' aka `m68hc11-*' targets this causes a phantom regression,
because they use 16-bit addressing and therefore `.dc.a' emits 16-bit
quantities causing relocation data constructed in assembly not to be as
expected. Previously input was rejected by `strip' with a `bad value'
message and now it is accepted, however due to the relocation data error
the relocation number is not one of the unsupported ones and the tool
completes successfully, which scores as a test failure.
Disable the test case for `m6811-*' and `m68hc11-*' targets then, as it
is a test case bug rather than a problem with the relevant backend. A
separate change to the test case is required to correct this problem, at
which point the test case can be enabled for the affected targets.

Speed up direct linking with DLLs on Windows (2/2).
This patch deals with the generation of the import library on the fly.
The implementation is inefficient because the linker makes a lot of
calls to realloc and memmove when importing the symbols in order to
maintain a sorted list of symbols.
This is fixable by relying on the fact that, for every linked DLL,
the list of symbols it exports is already sorted so you can import
them en masse once you have found the insertion point.

Speed up direct linking with DLLs on Windows (1/2).
This patch deals with the auto-import feature. There are 2 versions
of this feature: the original one, which was piggybacked on the OS
loader with an optional help from the runtime (--enable-auto-import
--enable-runtime-pseudo-reloc-v1) and is still the one mostly
documented in the sources and manual; the enhanced one by Kai Tietz,
which is entirely piggybacked on the runtime (--enable-auto-import
--enable-runtime-pseudo-reloc-v2) and is the default for Mingw and
Cygwin nowadays.
The implementation is inefficient because of pe[p]_find_data_imports:
for every undefined symbol, the function walks the entire set of
relocations for all the input files and does a direct name comparison
for each of them.
This is easily fixable by using a hash-based map for v1 and a simple
hash table for v2. This patch leaves v1 alone and only changes v2.
It also factors out pe[p]_find_data_imports into a common function,
removes old cruft left and right, and attempts to better separate
the implementations of v1 and v2 in the code.

Fix infinite recursion when printing static member with typedef
The original problem was fixed (see related PR 22242). But using a typedef
as the declared type for a static member variable, as commented in this PR,
is still causing gdb to get into infinite loop when printing the static
member's value. This problem can be reproduced as follows:
% cat t.cc
class A {
typedef A type;
public:
bool operator==(const type& other) { return true; }
static const type INSTANCE;
};
const A A::INSTANCE;
int main() {
A a;
if (a == A::INSTANCE) {
return -1;
}
return 0;
}
% g++ -g t.cc
% gdb -ex "start" -ex "p a" a.out
The fix is rather trivial - in cp_print_static_field(), should call
check_typedef() to get the static member's real type and use it to
check whether it's a struct or an array.
As Simon suggested, I've added a new test case to the testsuite
and am passing the original type, not the real type, as argument
to both cp_print_value_fields() and val_print().
Re-tested on both aarch64-linux-gnu and amd64-linux-gnu. No regressions.

Change target_read_string to use unique_xmalloc_ptr
This changes the out parameter of target_read_string to be a
unique_xmalloc_ptr. This avoids a cleanup and sets the stage for more
cleanup removals.
This patch also removes a seemingly needless alloca from
print_subexp_standard.

This is a regression for the corner case of a hidden symbol in a PIC/PIE

old-style GOT relocation. In this case, depending on the link order,
the R_SPARC_RELATIVE dynamic relocation for the GOT slot needed because
of the old-style relocation can be replaced with R_SPARC_NONE coming

set varsize-limit: New GDB setting for maximum dynamic object size
This is a command we somehow forgot to contribute at the time the Ada
language was first contributed to the FSF. This command allows
the user to change the maximum size we allow when reading memory
from dynamic objects (the default is 65536 bytes).
At the moment, this limit is only used by Ada, and so the implementation
is kept inside ada-lang.c. However, it is conceivable that other language
might want to use it also to handle the same kind of issues; for instance,
this might be useful when handling dynamic types in C. So the name
of the setting was made language-neutral, to allow for this.
Note that an alias for "set var" needs to be introduced as well.
We are not adding a test for that, since this is a feature that is
already exercized by numerous existing tests.
