records: Support custom 'this' identifiers.
This lets record users choose an identifier other than 'this-record'.

* guix/records.scm (make-syntactic-constructor): Add #:this-identifier.
[wrap-field-value]: Honor it.
(define-record-type*): Add form with extra THIS-IDENTIFIER and honor
it.
* tests/records.scm ("define-record-type* & thunked & inherit & custom this"):
New test.

records: Allow thunked fields to refer to 'this-record'.
* guix/records.scm (this-record): New syntax parameter.
(make-syntactic-constructor)[wrap-field-value]: When F is thunked,
return a one-argument lambda instead of a thunk, and parameterize
THIS-RECORD.
(define-record-type*)[thunked-field-accessor-definition]: Pass X
to (real-get X).
* tests/records.scm ("define-record-type* & thunked & this-record")
("define-record-type* & thunked & default & this-record")
("define-record-type* & thunked & inherit & this-record"): New tests.

records: Make 'report-duplicate-field-specifier' available at expansion-time.
Fixes a regression in 'guix pack -R' introduced with commit
c2dcff41c2.  The imported modules of
'c-compiler' would be compiled in this order: first (guix records),
then (guix search-paths).  Consequently,
'report-duplicate-field-specifier' would be reported as unbound while
compiling (guix search-paths), leading to a build failure.

* guix/records.scm (report-invalid-field-specifier)
(report-duplicate-field-specifier): Move within 'eval-expand'.

records: Detect duplicate field initializers.
* guix/records.scm (report-duplicate-field-specifier): New procedure.
(make-syntactic-constructor): Call it.
* tests/records.scm ("define-record-type* & duplicate initializers"):
New test.

records: Adjust to test changes in 'record-abi-mismatch-error'.
Fixes a test failure introduced in
de5cbd4a38.

* guix/records.scm (abi-check): Refer to TYPE in an unquoted context so
we get at the RTD.
* tests/records.scm ("ABI checks"): Adjust 'catch' handler to changes
in the 'record-abi-mismatch-error' arguments.

records: Adjust 'record-abi-mismatch-error' arguments.
Previously, 'display-error' (as used by 'warn-about-load-error', for
instance) would be called with a wrong number of arguments when a
'record-abi-mismatch-error' was caught:

  warning: failed to load '(gnu tests install)':
  Backtrace:
  [...]
  ERROR: In procedure display-error:
  Wrong number of arguments to #<procedure display-error (_ _ _ _ _ _)>

Now you get warnings and error reports as intended:

  warning: failed to load '(gnu tests install)':
  In procedure abi-check: <openssh-configuration>: record ABI mismatch; recompilation needed
  warning: failed to load '(gnu tests ssh)':
  In procedure abi-check: <openssh-configuration>: record ABI mismatch; recompilation needed

* guix/records.scm (print-record-abi-mismatch-error): Remove.
Remove top-level call to 'set-exception-printer!'.
(abi-check): Use arguments as expected by 'display-error'.

records: Make a couple of procedures available at expansion time.

(make-syntactic-constructor): Add #:abi-cookie parameter.  Insert calls
to 'abi-check'.

Use it and emit a definition of the 'current-abi-identifier' for TYPE.
* tests/records.scm ("ABI checks"): New test.

records: Use 'make-struct/no-tail'.
