Sometimes when implementing a Formatter it's helpful to use the fmt
package without invoking the formatter. This new function, FormatString,
makes that easier in some cases by recreating the original formatting
directive (such as "%3.2f") that caused Formatter.Format to be
called.
The original Formatter interface is probably not what we would
design today, but we're stuck with it. FormatString, although it
takes a State as an argument, compensates by making Formatter a
little more flexible.
The State does not include the verb so (unlike in the issue), we
must provide it explicitly in the call to FormatString. Doing it there
minimizes allocations by returning the complete format string.

Historically, Objects in go/types were canonical, meaning each entity
was represented by exactly one variable and could thus be identified by
its address. With object instantiation this is no longer the case: Var
and Func objects must be copied to hold substituted type information,
and there may be more than one Var or Func variable representing the
same source-level entity.
This CL adds Origin methods to *Var and *Func, so users can efficiently
navigate to the corresponding canonical object on the generic type.

These are straightforward variants of the existing Sprintf etc.,
but append the resulting bytes to a provided buffer rather than
returning a string.
Internally, there is potentially some allocation because the package
uses a pool of buffers to build its output. We make no attempt to
override that, so the result is first printed into the pool and
then copied to the output. Since it is a managed pool, asymptotically
there should be no extra allocation.

Adds a new, cryptobyte based, CRL parser, which returns a

to return much more detailed information, as well as leaving open the
option of adding further information since RevocationList is not a
direct ASN.1 representation like pkix.CertificateList. Additionally
a new method is added to RevocationList, CheckSignatureFrom, which is
analogous to the method with the same name on Certificate, which
properly checks that the signature is from an issuing certiifcate.
This change also deprecates a number of older CRL related functions and

Since a String method cannot return an error, escape fields that may
contain unsanitized values, and unescape them during parsing.
Add a fuzz test to verify that calling the String method on any
BuildInfo returned by Parse produces a string that parses to the same
BuildInfo. (Note that this doesn't ensure that String always produces
a parseable input: we assume that a user constructing a BuildInfo
provides valid paths and versions, so we don't bother to escape those.
It also doesn't ensure that ParseBuildInfo accepts all inputs that
ought to be valid.)

This method is unused and was not discussed in the API
proposals. Note that all error output goes through the
local sprintf which handles arguments specially.
Fixes#50760.

This patch reworks the handling of the DWARF DW_AT_bit_offset and
DW_AT_data_bit_offset attributes to resolve problems arising from
a previous related change (CL 328709).
In CL 328709 the DWARF type reader was updated to look for and use
the DW_AT_data_bit_offset attribute for structure fields, handling
the value of the attribute in the same way as for DW_AT_bit_offset.
This caused problems for clients, since the two attributes have very
different semantics.
This CL effectively reverts CL 328709 and moves to a scheme in which
we detect and report the two attributes separately/independently.
This patch also corrects a problem in the DWARF type reader in the
code that detects and fixes up the type of struct fields corresponding
to zero-length arrays; the code in question was testing the
DW_AT_bit_offset attribute value but assuming DW_AT_data_bit_offset
semantics, meaning that it would fail to fix up cases such as
typedef struct another_struct {
unsigned short quix;
int xyz[0];
unsigned x:1;
long long array[40];
} t;
The code in question has been changed to avoid using BitOffset and
instead consider only ByteOffset and BitSize.
Fixes#50685.
Updates #46784.

CL 331490 and friends added new API to package syscall.
This was a mistake that we need to fix before Go 1.18 is released.
